Why was I annoying enough that my boyfriend screamed he needed space & time (but that we weren't breaking up)?

Routinely (about once a week), my boyfriend, who drinks a lot, will say he's going out w coworkers or "the guys" and it's always "significant others not invited." I don't ever say anything even though I'm disappointed, & even when we ARE together, it's usually around other people (think, we meet at our fave restaurant after not seeing each other 5 days and he goes to sit at the bar instead of a table, and invites other people or talks to the bartender at length instead of me). He's never great at texting, but on these occasions (and other nights we aren't together), he'll disappear completely until like noon the next day. He did this repeatedly and when I tried to bring it up kindly "I think we have different expectations for communciation - I've asked if you could send me 1 single text in a night, that you got home safe, instead of disappearing till the next day & you keep not doing it"... he started screaming at me and calling me f***ing insecure. It's lame to me that I would even need to "ask" him to text me this much. Obviously he sees it as a problem. I'm not controlling or demanding of anything else though, so I do not understand why you'd need 2 weeks of "space/time" over this. He says we aren't seeing other people but isn't making any effort to fix things? How could I be this bad?

I should add that he routinely drinks 3-5 liquor drinks (in addition to more before we go out) then drives and I’ve felt the car swerve on more than 1 occasion so it’s not like I wouldn’t want a home safe text
