For the kids

Recently went through a nasty pregnancy dealing with my kid's father. He got me pregnant at the same time he was in a relationship with his other kid's mother who was also pregnant at the time. There was a lot of tit for tac. Nobody was tryna hear me out, that boy lied to me and said he wasn't with anybody when i got pregnant. He had everybody believing this wasn't his kid and after trying to convince everyone I was just like forget it and file for child support and be done with all of them. But as soon as I was getting ready to file the other mother reached out to me and now believes that this is his child and got the kids together to meet. She makes me feel like we can put our differences aside and raise our kids together. But the father that links us all still refuses to get on board and still does not want to meet his daughter he has with me. We finally have a court date coming up to establish paternity. I said to him since the mothers are on board and get along now, when does he want to meet his daughter, he said he don't. I just don't understand how he can wanna be there for the rest of his kids but not this one. The other mother insists that she'll be around no matter what cuz our kids are brother and sister. But how can I not feel funny that her son has their father but the same father don't want nothing to do with his daughter? She tells me to see what happens after the dna results come out and then go ahead with child support. But he been giving me his ass to kiss and been dodging taking a test before, so I feel like I can't wait and see for him to finally come to the realization that he has a daughter with me.
