Is separation causing this ??

I know my bf works almost the whole week and almost the whole day. I don’t have a job and I’m trying to get a job so I can spoil him. But I feel just alone. I mean I go out with my friends when I have money... I want to talk to talk to him and spend a little time but we can’t and it sucks becuz I want him to feel like relax from work and not annoyed by me. We FaceTime less than 20 min after that he plays fortnite with his boys. I also play fortnite I’m a gamer too but he doesn’t want me to play with him becuz I don’t take the game seriously, it’s funny how guys take it so seriously so I just fuck around. But he wants to win alll the time so he doesn’t inv me. Today he FaceTime me and told me want happen with work and he was piss off okay I’m there for him like “damn babe that sucks, wat else happen ?”... later on he asked me if I follow guys on my instagram (we delete our instagram to start over and start fresh becuz we agreed on it ,not to get mad over dumb shit) and now we got into a big argument and now we are in square one where he doesn’t trust me becuz of his insecurity... he doesn’t want to talk to me even tho I haven’t done anything to him. He’s just really dramatic, wants me all to himself but he barely talks to me... I just feel sad Becuz he’s the only person i want to talk to... I’m sorry if my grammar is off it’s just I have a lot in my head at the moment. Btw we are both 18.
