I (24M) was recently broken up with and kicked out by my now ex (32M). We were together for 3 years, and Polyamorous for a good chunk of it. He had a girlfriend (honestly don't remember how old she was) and I still have another boyfriend (29M). I'm autistic and often have problems with tone and phrasing, as well as ADHD and have a hard time with honestly a lot of things in life because of it. I am now getting onto medications and into therapy. We would often argue about scheduling, he would change plans on me a lot and even if it was in advance it would panic me because it felt that so often he was canceling our plans to do something with his other partner. She seemed very sweet and I liked her but I don't like having promises or plans changed a lot. I tried to talk to him about this a lot but he said I was being unreasonable and overreacting. I never meant to yell sometimes my tone or volume would be louder than planned. I never meant for anything to sound rude but I'm sure it did. I just have no idea how to fix it hence the therapy now. He would give me a spending limit as a gift then see something he wanted or have something come up all the time and he couldnt give that to me. It just felt like promises were always being broken. I wasn't perfect either, I let my mental health and cleaning go after my nana died a few months ago. She was like a mom to me, and I acknowledge he was probably right. I should have gotten over it faster and not let myself sink so deep. But recently he planned a nice weekend for the 2 of us, just because he wanted a final good weekend before he broke up with me. The day he broke up with me he kicked me out. So I am couch surfing at my mom's till I can get back on my feet but he knew my family situation has been rough. I'm technically not on the lease but I have proof I was sending him rent every month including the month he kicked me out. He kept some of my things because he promised to pay me back. And wouldn't allow me back unless he approved when I would come over. He moved his GF in only a few days after I was kicked out. And I'm worried my judgement is being clouded by my anger towards him. He is refusing to send me more than $100 per month but the having him pay me over time is making me uncomfortable. He is saying that I am being greedy, and that I'm not considering his needs right now. But every time I see the Venmo with a little "100/730" under it instead of the cute little emojis he would add before. Like it's slowly counting down to when I don't have to see his name again on my phone. It really hurts. I'm so mad, sad, and confused. I would just except all the stuff back instead if it meant I didn't have to stay tied to him. But I was talking to a friend because I decided to look up what my rights were and if there is legal action I could take. They said I'm an asshole because I am not considering his side. I truly want to understand, it's been a month now since the breakup and it just feels like this is drawing it out. It's not entirely about the money. I was just hoping a legal threat would end it all since he is ghosting me right now. And refusing to maybe find a middle ground between what he is paying me and the over $1000 worth of stuff that needs to be replaced now. Idk if I'm wording any of this right. I'm sorry if this one was long. I definitely need it for sure. But it just hurts right now and I want to know AITAH for considering threatening legal action just to try to end all of this?
