ex/boyfriend ghosting me

I’m 21 female he’s 22 male. we had an argument early friday and i was in a bad mood and asked him to drop me off at home (we live together) because i didn’t see my mood getting better soon and i just wanted some time to cool down from something unrelated to him (i told him that too). then he yelled at me to snap out of it and that i’m a child and why do i even need cool down time. then he said he was moving out. which just is a totally different mess i now i had to deal with. and i have abandonment issues so when he says that, it really fucks with me (which he is aware of). then he had his grandpa come and pick him up and then he broke up with me thru text. then later that night we talk and he comes over. i forgot what even started the bickering but i then wanted a second to cool down and get my head together and he then he again went off about me needing a second to cool off (i was only going to a separate room to listen to a few songs and take a breather) and then yeah. he then decided he was going to walk home and then i haven’t heard from him since (this was friday night.) but before he decided to go home, he told me he loved me unconditionally and everything’s okay and he was sorry. i texted him on saturday morning and my messages haven’t been read (it’s on facebook) and just say sent. then he was active so i deleted him. (on friday he blocked my number and snapchat) then last night he changed his cover photo of us to his guitar. i haven’t said anything to him since saturday and i’m not sure what to do. i still have most of his stuff at my place but i don’t want it to be over and he’s not communicating and idk my heads going wild and could use some non biased advice (: thank you for reading xoxo

[EDIT] the breakup text i’m referring to is him saying “i can’t do this”. no clarification because we were arguing before in text so maybe he meant he cant handle the arguing which i get
