Rant about my father in law

I hate my father in law.

When my SO (A) and I broke up for a few months back in 2017, my father in law tried getting with me. Sent me gross messages, dick pics, and would ask me to come over for sex. Keep in mind I was 17. When I denied him he started turning shit on me and telling A that I was trying to get with him. (I wasn’t and was able to provide proof, obviously)

He’s just got worse over the years. He would leave A alone for weeks on end growing up with no food, the only way A was able to eat was at school. I met him my freshman year and he was 110 pounds and addicted to pills. I helped him battle his pill addiction, but his dad would try to get him pills. His dad was one of his main suppliers.

He would take A to the bar as young as 14/15 and make him clean and tried getting him with his older lady friends (which A wasn’t interested in, he was 15).

Had a falling out with meth, he’s apparently clean now. He won’t allow me over to the house and has a grudge against me, but says once the baby is born in Dec then he wants to see the baby, but not me. Which I’m not cool with at all. When he found out me and A were living together and engaged, he flipped out. 🤦‍♀️ he uses A. It’s annoying and A just allows it to happen. He just moved 45 mins away, and had A pack his entire house and move everything, even tho he invited A over there to help. He had 2 months to pack and made A do it last minute - then ignored A for close to 2 weeks after he had helped him.

He tries to get A and his sister to hang out but will ditch them both constantly. A’s sister completely cut off her dad because he was horrible to them growing up and she got sick of his inconsistency.

He always tries telling A that I’m not worth it and he made a mistake getting me pregnant. A and I been together since I was 14, and his dad hasn’t liked me since, but especially after I denied his advances.

I’m frustrated. I don’t know what to do anymore. It’s tearing me and A apart. He doesn’t understand why I don’t want his dad around the baby and doesn’t understand why I don’t like his dad. I’m over everything.
