HELP! He’s back!

So back story: me and my boyfriend moved in together after a few months of dating. And let me tell you it was TOXIC! He stopped talking to me, paying attention to me and basically gave up on our relationship and broke up with me Monday night. Wellllll... Wednesday he left Texas and went home to NM. And is just now coming back today. The day he left, I blocked his number and all social media accounts because I didn’t want to see what he was talking about, doing or anything. After returning today, the first thing he asked is why I blocked him and I told him that it made it easier for me to forget and that I didn’t want to talk to him and he just said ooooookay with a smart ass tone. 🙄

Then he tried joking around with me and shows me his new 9mm gun and then he just sits next to me on the couch and says nothing. Take note when he broke up with me, I cried my eyes and poured my heart out to him and all he had to say was “okay now can you get out of my bed?” And he was a total dick about the whole thing but NOW he wants to talk and be cool with me🙄

Him being gone helped me control my feelings and look at things from a more positive perspective BUT I’m ready to fuck his shit up😬 (I won’t but I want to) it’s a little too late to try and have friendly conversation.

Why do you think he’s trying to talk to me now? And how should I deal with this while living under the same roof (until I find a new place)?

UPDATE 1: he just told me that if I wanted to have sex with someone not to do it on his bed or couch but the futon was okay 🤨🧐
