I shared your post with a female friend, She seems to think that Jennifer was just looking for someone to comfort her. Jennifer may not actually be interested in pursuing a relationship with you. Actually that is what I would suspect.
As a Christian, this is part of the reason that I believe that sex outside marriage is bad. I certainly have been tempted to fornicate, and I do not believe that I am better than you.
But because of the tempation to sexual immorality, each man should have his own wife and each woman her own husband.

I am merely expressing, that I worry for you. Your situation is painful, and you need to make some tough decisions. Know that though you have made a mistake, you do not need to continue making mistakes.
In an ideal world, you would marry your fiancee. If marital counseling would work, then get married. It seems like this is not really an option for either of you. Though, you are both still tied to this child and both have to care for her, but if you and your fiancee are falling further apart, then marriage will only result in an ugly divorce. I don't think that is your best option.
As I've said earlier, I don't think that pursuing Jennifer is an actual option. However, you should give her a call though and talk it over. You've waited 5 years for this woman, so you might as well double check that she really was just wanting someone to comfort her for a night. Maybe she is interested in an actual relationship with you.
I do think you have a responsibility to be honest with your financee. If you feel marriage will not solve your problems, then your fiancee probably feels the same. Knowing that you cheated on her is something she ought to know before she considers marry you. Again, it doesn't seem like you should marry her.
I would also encourage you to go to a church *. Church is designed to give good friends. Friends that you can trust and give you advice on what to do with your life. It's designed to be the hope of the world. I have church friends that have gone through drug abuse, relationship abuse, etc. Church is a place for broken people. That's why I attend to regularly.
I would also recommend that you save yourself for marriage. You've already had one child, whose mother you may not marry. You will only make the situation worse if you make another woman a mother.
Your life isn't over yet. Moses was a murderer, yet God called him to lead the Israelites for 60+ years. He was the Godly man in church history. Noah was a drunk, yet he built an ark. Paul murdered Christians, yet God called him to be the apostle that replaced Judas. There has never been a better church planter than Paul.
Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; Thy rod and thy staff comfort me
- I would reccomend a Protestant church, probably a baptist church. But that's just my opinion.
