Ok try to concentrate....my boyfriend has 2 kids by the same woman. The son is 3 yrs old. He has had split custody of the son since they broke up. They also have a daughter together. She is 16 months. My bf's ex cheated on him...she had just gotten pregnant when they split up. She said the baby was the other man's. All of the sudden out of the blue, when the daughter is 12 months old, the ex says she wants a paternity test because she thinks the baby was really my bf's...because her current boyfriend was getting ready to leave her, and he demanded a paternity test. Lo and behold, it was my bf's baby, so he has to pay for 3 months of child support while he and the baby have an "introduction period." SO...due to her f*ck up, he has to pay child support Had he known from the beginning that the daughter was his, he would've gotten 50/50 custody and not had to pay any child support and wouldn't have missed the first 15 months of his daughter's life. It took 4 months to finally get visitation with the daughter, because the ex is an evil biatch. So they go to court, work out the 3 month intro period. Two weeks later, ex calls boyfriend and says she is getting a second job...and she wants to cut the intro period in half. But...she doesn't want to cut the cs in half....because she is just a money grubbing biotch. SO, bf agrees to pay her the full amount because by the time he paid for the lawyer to go back to court, he'd spend more than he'd save. So that is how he got screwed.

I was trying to avoid going into that whole long story..but since you weren't satisfied with any of the previous answers, you got it. Do you understand everything now?
