Need advice about my wife

[ChrisSuperG]

Me and my wife are both 28. We have good jobs and make a reasonable amount of money. We have been together for 5 years.
I love her very much. She is to be frank my perfect type. She could easily be a model. Whenever she goes out she gets hit on CONSTANTLY. Whether i'm there or not actually.
Me, not so much although I have no problem attracting women. I am above average and take care of myself, but I couldn't be a male model or anything.
Generally our relationship has been fantastic. Neither of us has been unfaithful and we are very much in love. I certainly love her very very much.
The last six or so months have been stressful however. Work has been into overdrive for both of us, and although we've made a reasonable amount of money and bought our first house either of us getting home before 7pm is rare. Basically we've been exhausted and have neglected both sex and our relationship, although not for any other reason than time and being exhausted. My feelings haven't altered one iota and neither have hers.
Fast forward to around 2.5 months ago when we were both invited to separate reunions with old friends across the country (neither of us are originally from the area we're living in now). It was a great opportunity for both of us to blow off steam after working so hard and neglecting life for a few months, although we were both disappointed it wasn't going to be with each other.
So we kissed, told each other how much we loved and will miss each other, and I went across the country to my hotel and she went to hers.
Lets just say, we had VERY different weekends.
Hers involved going to a party where in her words, the most good looking guy she has ever seen approached her. Apparently he was a friend of a friend of someone else at the party. She basically said every woman there was looking at him and she was just on a high that this guy approached her. She didn't plan on anything, but everyone was drinking heavily and she ended up in bed with him....... FOR MOST OF THE WEEKEND.
When she came back she was the most loving attentive girlfriend you have ever seen. I was still too tired/exhausted for sex, but literally she was like a stepford wife in the weeks that followed. I stupidly just put it down to her missing me and loved that she loved me so much.
Fast forward again, she broke down and said she couldn't cope with the lie anymore and told me everything. Prompted I'm sure by her finding out that morning that she's pregnant. There is barely any possibility of it being mine.
She is the most sorry and frightened woman you have ever seen. She even asked me to physically assault her because she is so angry and upset that she cheated on me. She will do ANYTHING I want to make things ok. It's a bit scary actually. She is frightened and literally shaking at the prospect of me leaving her.
If i'm honest with myself I think most of the fear is about the baby. She is crying saying she can't get rid of it and she is terrified of keeping it and raising it alone.
I was completely and utterly numb and heartbroken.
I said to her that before I go any further, I need the truth. Literally every second of what happened that weekend or I'm out the door. I knew this was a double edged sword and that the reality and cold facts could destroy me, but I'm one of these people who can't not know.
The facts were horrifying and made me physically sick. I actually threw up. Basically my girlfriend was this guys personal porn star for the weekend. Some highlights:-
It was the roughest most aggressive sex she has ever experienced, and she enjoyed every minute of it. It was the best sex she has ever experienced.
She had several powerful and intense orgasms during their weekend in bed. She has never ever cum like this before with anyone or solo.
His dick was the best she has ever taken. 8" which rubbed all the right areas and he could keep going again and again.
They didn't use protection (obviously) and he came in her mouth (she swallowed) all over her face, her tits and inside her several times during their weekend together. After he came on her tits he pushed her back on the bed and scooped up his cum with his finger and FED it to her.
He smacked her during sex (not too hard), her ass and her face and before she had time to even feel the pain or react he would whisper something or do something passionate that made her just let him "keep going" so she said. So he basically taught my girlfriend to enjoy some BDSM that weekend. Awesome.
He caught some of the above on his camera phone. So there is a video somewhere of my girlfriend basically acting like a pornstar in a cheap hotel room.
So, Gooners. I can't say I didn't consider the implications of asking, but f***ing hell I have had my heart firmly ripped from me.
Currently therefore I have a girlfriend who is pregnant by a male model BDSM hero with a huge cock, who is going to have his baby, and who is so sorry she will do whatever the f**k I want so that I can somehow get over this and stay with her. Basically I can treat her however I please as long as I don't leave. It's fine if I hate her for the rest of my life even as long as I stay with her.
We have been talking about marriage and kids this last year and she is desperate for me to commit to that still. She keeps promising to spend the rest of her life making this up to me and will be the perfect wife I could possibly want.
I don't even know what to think right now. I feel like every sense I have has been shorted out and I am now totally numb.
My first instinct is to just wait for her to work in the morning, then pack up all my stuff and just leave. I am not the type of guy to raise another guys baby. Especially now I know the full circumstances of how it was conceived. The house is in my name and I could sell and switch to a different end of the country with my job very quickly. I feel so grateful for that right now.
So I can literally leave and never speak to or hear from her again.
The only problem is that I am so in love with her. I don't feel like I'll ever get over her. f**k. I'm hesitating. I'm second guessing myself.
What do you think? Is it possible to overcome a situation like this? I can't think how. I simply cannot raise this guys kid. I can't.
My heads all over the place. Rational thoughts would be awesome about now.

Has your father-in-law let you back in your office yet?

Lol that's going back a bit

Mistake 1: Getting married—too much risk in it nowadays for guys. Even prenups can be worked around.
Mistake 2: Being a beta—should have dropped her ass the moment she told you. Cut your losses and rebuild.

Was the handsome guy Giroud by any chance?

[DiamondGooner]

Tell her you'll accept her offer to beat her for forgiveness, make her sign a waiver, beat her .......... then leave her.

Its the right thing to do.

Also you may want to look into your urhmm technique, just because a guy is good looking it shouldn't make a "satisfied" woman feel the need to jump on the next 7" she see's.

Something was obviously missing at home, learn how to row your boat better my friend and then your woman wouldn't go looking for glory elsewhere.

Bang her mum out of spite.

Leave her. Sounds like she let that dude do thing to her that you never did. You'll never get those images out of your head.
