Me (38F) and child father (38M) have has a on and off relationship for the past 7 years. We have 2 kids. When we broke up, he immediately got in a relationship with a girl he was cheating on me with while I was pregnant. They didn’t work out. A year later, he met a lady online and married her after 1 month of meeting. She moved with him and shot him in the arm shortly after. We found out she has an extensive criminal background after that. He still continued to date with her. He switches out women constantly since our split. He has had several instances where he has had drugs (pills) around my children. He’s experimented with other drugs as well. It all started right before we broke up but I wasn’t aware until after. He once got caught having pill sex with a random women by our child. He has a habit. It’s controlled lately but it has been an issue. I thought he got hisself together and we tried to fix things between us (foolishly). But he randomly got into astrology over the past few years and an astrology app told him that a woman he was dating before is his soulmate so he wanted to be with her to explore that. (Astrology is also why he got married). This new girlfriend sells drugs (weed). She is also trying to get pregnant with his child. I don’t want her around my kids. He keeps picking unsafe/risky women and brings them around my kids. AITAH for putting him in child support knowing that if she gets pregnant my kids will come last financially? He pays non-court ordered child support but it’s inconsistent. He once went 6 months without paying me a dime. It’s not fair that it falls on me. AITAH?
