how do i (F24) move from here out with my ex (M25) ?

My ex and I have currently been broken up for 2 months. i broke up with them first because they followed a random person of the opposite sex at a bar while out with their friends. then we worked it out and got back together, then they decided to break up with me because they came to the conclusion that their depression was deeper than just losing me and they needed to figure themselves out. honestly they were never working on themselves. i started to hear that they’ve been lying to me about things and doing other things besides actually getting the helped they needed. i was trying and trying to make things right. to support and be there for them and i kept getting shunned and pushed away. asked to leave them alone and that a relationship isnt what they want rn. finally i decided to cut things off with them. after that they basically replied with a whole lot nothing making things even more confusing. we’ve been off and on contact, recently they’ve been sleeping over my place for the last 3ish weeks. I was supposed to move back home back in august but because of the break up i extended my stay, in hopes we can figure things out. now with halloween coming up i asked if they were planning on going out with friends, you know it’s halloween of course. it lands on a friday of course. they said they don’t plan on doing anything on halloween… come on dude…. be for real. it makes me uncomfortable knowing that. so i asked if they wanted to go down home with me. they said no cause they don’t wanna go down there. i’m thinking in my head??? why not??? realistically in my eyes if they were planning on getting back together they would put that effort to go down home with me especially if they have no plans up here. now they didn’t plan on staying over tonight as well. weird. last night they just asked what’s wrong all night. i decided to keep to myself honestly, because anytime i talk about how im feeling it just seems like they get defensive and think im trying to argue. when really im just telling them how i feel. and thats exactly what happened this morning. so i talked to him this morning telling him how i think he will end up going out with friends and right off the bat he got defensive and said he wasn’t about to argue about that. but i was just trying to explain why how it made me feel like him not wanting to go home with me makes me think it’s because he never planned on getting back together with me. he got defensive again and said he’s not doing anything and said just cause i don’t want to go home with you doesn’t mean anything. i started to cry. i just wanted to explain to him what i was thinking. i couldn’t sleep well because i was just upset and thinking how all of this is almost over. leaving my job. my friends. him. he left giving me a kiss. i decided to text him “this is why i didn’t want to tell you what was wrong. i don’t want you hating me.i wanted to be with you for halloween, that’s all. to dress up together. idk what i was expecting. in my eyes it just seems you’re not planning on getting back together atp. “ no response. feel so unseen. unimportant. just feels like it’s the end of things. hurts. not sure what to do here on out. i move back home in a week.
