what would you do? (neglect, mind games, court)

you're chronically disabled, solo mommed, no babysitters or relatives for 7 months you find out your bd is dating ur hs bully she confides to u that he hid you and your pregnancy from her, so "as revenge", she took out her birth control, got pregnant, and miscarried. u get kicked out of ur house because the landlord wants to sell it you tell your bd (300mi away) to step tf up and come take his daughter for a while so she doesn't have to shelter hop with you, and she can be around loving family. you find a place, go to get her, and find she has all these new medical problems. 3 days after coming home to you, all conditions are gone. all the problems they spoke of are non existent. except she now has a fear of her crib and being left alone. you express these concerns to bd, he doesnt address any of them, and all the sudden, gf thinks that bd and i are too friendly! she sends you a VERY long aggressive message. bd's sister (lives with them and their mom) calls you IN TEARS, telling you about the rotten things they were saying about you TO and in front of your daughter, how she was neglected and mistreated. when she was cared for, it was bds gf! and not bd. guess who did all the shit talking? not bd! you cancel her trip down planned for 12/23-1/3 (her birthday). you point out how none of your concerns were even acknowledged, and so you would like him and gf to come to you for a little to see for yourself how he cares for her. at first its "youre keeping her away from her family!! if its something personal, u know thats not right." you tell him you stated your concerns cut and dry, he says "a couple hours on her birthday should be fine". you file a family court petition (there is no custody agreement, child support, or responsibility/accountability at all), and youre waiting to hear back closer to the date, he claims he cant come because "bills", but to please let him know when he can come to get her. you havent heard back from family court what do i do with this dodo bird.
