<human>: Can you give me a shortened version of the text?

In September I was away on business for two weeks and my then wife, whom I had been with for 6 years cheated on me. She was immediately remorseful and told me the next morning. It was very hard for me to accept, but I eventually decided to forgive her and moved forward.

Over the course of the next month we began to drift apart. We had no free time together because of conflicting shifts at work, and when we were both home we were off doing our own things...

After a tough discussion, we decided it would be best to separate, at least for the time being. We both ended up seeing other people within days, it was awkward. She was dating this one older guy, and I had become a bit of a whore. 

Fast forward another month or so, me and the ex started talking more again. She had confessed to me that she felt nothing with the new guy and that she wanted to be with me. I felt the same... I was unhappy without her.

As of earlier this week, She found out she is pregnant. 

I am devastated...

My SO doesn't want an abortion. I am guilty of giving her a biased opinion on the matter, but regardless, I think she wants to keep it. 

I love her so much, but how could I possibly support her keeping it? I'm sick to my stomach thinking about it...
<bot>: SO got pregnant whilst we were having a trial separation. She doesn't want an abortion. I love her, but could never support someone else's child. NEED WORDS OF WISDOM
