Am i overreacting

Recently my bf has been really distant and non chalant lately. He works a lot as a security at a hospital and pays bills. But since we’re 2-3 hours apart, we used to rely on calling each other. Now there’s been an issue where I seem to be “ nagging” about him calling me more , in which he hasn’t called me himself since the 12 of February. I’m not sure what to do. Is he cheating on me or something. I keep asking him do u wanna break up and he says he will try. But then he ends up “ sleeping “ whether it’s in the afternoon or evening. I swear to God I have never met anyone who sleeps as much as he does. Im doubtful whether he actually does , and i secretly ( unintentionally) have one of his emails logged in where I can see he watches YouTube. I’m Turning into a helicopter gf, and my trust issues are triggered 24/7. It’s like I need to know what he’s doing who he’s with. I know I have a lot of trauma , so I’m asking him to break up with me if he can’t handle a relationship with me and do the bare minimum which is show affection, be present and call me, he says he will but never does. I know i have my faults, I really don’t want to leave him, but I have tried everything and communicated in every way . Yet I get fake reassurance. It’s gotten to a point where my anxiety is severe, and I cry every single day. I don’t have friends or family members who won’t judge me. I understand I nag, but it’s really irritating when the person you love is putting up a wall to a point where it feels like everything I say is at a brick wall, and I feel guilty just to speak up for my needs., to which I can’t help but “nag”. It’s been a month and half , and the phone calls we had have always been initiated by me and end up being tense. and I really would appreciate any considerate advice, as my head is filled with overthinking thoughts
