Narcissistic BD

Please no DMs. This is a bit of a rant but I’m so over it. I failed my unborn baby and my heart hurts for him. I’m 2 days away from induction at 37 weeks & BD blocked me. I woke up to a text related to a post from one of those are we dating the same guy groups I’m not even a part of bc he’s been posted in there and some of the girls know me. I sent him a screenshot of the text saying how I was frustrated that I’m getting messages and to please handle his affairs better. He took that as an opportunity to turn it around on me and used it’s as a pathetic excuse for why he can’t deal with me anymore and how I’ve been “obnoxious” lately. Like I want to have it rubbed in my face that he’s out there fucking around while I’m barely getting an ounce of support from him dealing with my high risk pregnancy. I’ve been nothing but fair wanting to keep shit out of court and go through mediation. Sure I’ve been emotional most likely but that comes with the territory doesn’t it? He “can’t stand me” or has “grown to hate me”. If I stand up for my self I’m punished with being blocked or he puts me in “time outs” because he can’t deal that I want the ask for the bare minimum. As much as I want our son to have a father I’m just at a loss at how a grown man nearly 8 years old than me can behave this way. I don’t have the energy to be nasty but he pushes me so much.
