My youngest sons father has legal custody. I had really bad post partum and my son was removed and placed with him while I got mental health support. During that time he filed for legal custody and it was awarded to him. Our son is three and he was taken at a month old. I just feel our bond isn’t super strong and his father has not forgiven me for our relationship not working and him feeling neglected but I was diagnosed shortly after with borderline personality disorder. Relationship was good bad and ugly. But it was over two years ago. He holds resentment and hasn’t forgiven me which I’m okay with I can’t keep apologizing bc I wasn’t well and just dwelling on it. He pawns our son. Visits are becoming shorter if they even happen, he claims this single father thing as if I’m a deadbeat mom. He recently got a gf in the last 6 months and I’m completely done emotionally with him. I’m currently pregnant and although single I don’t hold those feelings they died awhile ago. But today was trick or treating and I didn’t even get a pic with my sons costume on nor was I able to take him trick or treating. As parents all I’m trying to do is coparent and still enjoy these memories with my son but he seems so against it bc he doesn’t want our paths to cross. I’m trying not to resent him but he’s taking away precious years from me. It breaks me inside. I feel like he trying to replace me to have the family we couldn’t and he totally disregards how I feel about the lack of visits, he feels he has to sit In and supervise. He stays about a hr then he’s gone bc they have outstanding plans. But I’m tired. He says things to get his rocks off if I respond with a bigger trump I’ll be blocked or blantantly ignored for weeks like I’m on punishment. I reach out he doesn’t answer or respond to text when it comes to even talking to our son, or about days I would like him to visit. It went from weekends and days throughout the week if schedules allow to maybe a Saturday for a hr. I feel it’s bc him and his partner spend time together with there kids. I’m currently in counseling and on medication. I don’t feel like I’m a risk to my son I wouldn’t hurt him. I want to get visitation rights through the court bc this is ridiculous but any advice?
