I never know if I'm in the wrong or right. I don't know if I have wrong people around me or not (I don't think so but sometimes this feeling just kicks in).

As example: I am living with my favorite person right now, going home again in 3 days after 2 months that I have stayed here. I loved it here, but as always I'm worried he might don't want to visit me for some weeks after that. I could understand if he would want to be alone for some time, he wasn't alone since 2 months except for showers or when he had to go to the toilet. On the other hand, he always said he doesn't feel bothered by me, I could always be here, he like me around etc.

So in 3 days I'm going home and asked him "will you come visit soon, me when I'm at home?" and as always, he just got bothered or angry, idk what exactly, probably annoyed. He said "I don't know, don't ask me stuff like that"

This made me really insecure and now I'm worried I will see him in months again, I was hoping that 2 weeks would be the maximum, and then he might visit again... but he sounded so annoyed. He was never annoyed while I was here but questions like this make him always mad.
A lot of times I can't even really talk with him because he just gets annoyed. If I see he has a bad mood and I ask him what's up, he just wants to be left alone. If he does some things on the internet and I ask him what he's doing, he just says "something".
It always feels like he doesn't want to talk and it makes me so god damn angry. I would love to shout at him but I know this would lead to nothing
I can't even talk with him about it because he would just get annoyed that this bothers me so much

I don't know if I should "fight" for a better communication or leave it how it is. I don't know if I am overreacting and maybe I'm just too clingy?

at least I got it all out now
