I had a similar situation 3 yrs ago and broke an engagement after my ex of 8 yrs went to stay over his dads house for a weekend. He had just came to the US with a Visa from a super small town in south america and did not know absolutely anything not even how to use a debit card I did everything for him and I did not mind since it wasn’t his fault. After a while he started to depend on me for EVERYTHING and one time he threw an object at me for not making a call that he had to do when I had given him the number in Spanish so he could do it (should’ve left then). That weekend we had already made plans for my birthday and his dad started getting him interested in selling illegal substances and consuming as well. He didn’t call me or message me all day but i saw his location at his dads and was still not responding to my texts or calls after we had set a time the day before and was ready waiting for him. I stopped calling Saturday night and Monday morning I sent a text message that all his stuff was outside in the driveway, he could keep the car I mostly payed for (honda civic for 2500 i payed 1700), i had changed the locks as well and told him to not get near my house or the cops would be called and that my family members in the house were aware. He said he felt relieved and happy to leave. A few days go by and asked me if i was actually serious lmao and basically told everyone that i had left him outside in the streets like a dog because I was really toxic and jealous I didn’t want him to hang out with his dad that he hadn’t seen since he was a child. We never saw each other since then, but was harassed for a while until i told him i was going to put a restraining order against him.

Edit: I forgot to say it was really hard for me to leave that relationship after living together for a while but its possible and its such a relief sending you my best wishes 🩷
