I would only say to really think about this before you take any decision. Say you agree to work out with your wife, but it fails. You just let go of your GF you say you love. Even the other way is true.
If you decide to work it out with your wife, i think you will have to consider these.
1: Are you really willing to forgive and also forget all this and start fresh.
2: Is she willing to do the same?. What is the past comes up? Will you both start rehashing it or agree to bury it for good.
3: Are you willing to agree for her to terminate her pregnancy? Will you lose respect for her by these actions? If you lose respect for her, how will you love her?
4: If she's willing to go this far with OM, and god forbid if it happens again, will you be able to take it?
5: Will you be able to completely throw away the feelings you have for your GF and go back to your wife with 0 regrets?
So on hand you have a GF with whom you can really start fresh, no good or bad history, but where you have to bury you past and move on. And on the other hand you have your wife, known history. But even here you have to bury your past with your wife and start fresh....
