I've been there, but I actually had a few partners as I rebelled against men when I got divorced, I got drunk all the time and wasted my life away for a whole year. No matter what, when the baby is born get the papers from the state for help determining the father for child-support reasons. He will either take responsibility or not, but at least you would know for sure, and the baby will be able to know about its family if it wants to. Thats about all you can do, unfortunately, men get the better end of the deal if they want. But thats when us woman just have to stand strong and change your life for the baby. When he does find out he is the father, I would give him one more chance to make a relationship, no matter what you think of him by then, because it's the baby who suffers in the long run. My daughter did not officially find out who her dad was until she was 5 for my own reasons, and I regret it all the time. I had a dna test with the guy who I thought deeply was her father, found out she wasn't and I lost it, I was asshamed of myself, and was scared to go through another dna disappointment, well turned out it was a match with the second. It was a friend I had a one night thing with because we were really good friends, but not each others type, well, two minutes into the whole thing, we both realized it was wrong, so when I took the dna test, we thought that there was probably no chance, we were wrong. Proof that the Pre-Ejaculation is also pretty good stuff. LOL. Anyways, my daughter suffered, and now she has an excellent relationship with him, and I feel bad that they lost all that time from knowing each other. So, in other words, get through the pregnancy as stress free as possible, then do the test and go from there. I know that it makes you just want to hate this guy, but think of the baby. He will realize his mistake when he is proven to be the father, then you can yell at him and express the anger. Take his butt to court, and get some help. Take it easy, and good luck! Don't worry, it will all work out in the end.
