I feel my lifes wasting away because my baby mom?

So since we started dating things were good, I think I was her rebound as she just got out of a 4 year on and off relat. She got pregnant n we got in a huge fight n I said fine get out then cuz she stays disrespecting me and calls me names after I paid her cc bills twice and done and I was very respectful n loving. I think she found this to be weakness in me cuz I did worry a lot. So our daughter was born she's 4 month I haven't seen her in a month. I said sry n did everything I cud to get her to come back. She keeps saying she loves me and is gonna move back n keeps saying this. This has been going on since march now. So I continue to talk about our relat and she says I'm overwhelming and smother her. I asked her what I can do to get her back w me n she says nothing when she's ready shell move back but if I keep talking bout it won't get her back any sooner. We been dating a year and 2 month. So she says there's nuttin I can do but then again says I haven't been trying. She isn use to a nice respectful guy so she finds weakness in me. I seem to can't stop talking bout our relat n all. All it does is make her wanna hang up n get stressed. She's living back w her dad since march I have tried goin there every am before work n right after work I was getting drained, I tried not talking to her but she wud contact me, I tried being cool acting like nuttin bothers me but I can't cause it does, I just want our fam together but she keeps saying well u did this u kicked us out u r the one this and that, y can't she just stop holding this over my head. Twice now she has said screw it I'm just gonna come back and pray u won't hurt me. She gets my hopes up then nuttin ever changes. We are going thru court right now she has been getting public istance n she clearly wants my money for child support. We go to court at the end of this month. But I need advice on how to stop stressing over this n how to not talk about it. If she wants to come back she will I no but it isn't that easy. Help!!!!
