Partner & his phone

Please let me know if I have a problem that I need to work on.. my bf and I live together and I can careless to be on my phone, this guy can be glued to it.

We don’t have social media so even more I wonder what could he be possibly doing. There’s times he’s on it randomly (we’re watching a show) for 10 min I’ll eventually ask “what are you doing”. He gets bothered, I do ask him often (I won’t lie) but it’s a problem when he’s drinking (alone) and he stays outside with his phone till 12-2am so last night this happened. I went out at 1am and he’s on it, I ask “what time are you coming to bed? What are you doing?” He was on his phone but started with his comments when I asked, what are you doing 2x. “Here we go Nataly, always pressing me about my phone” now my bf has his days where he’ll ask me (I’m not really on it) but I never get annoyed or defensive at all. I show him and that’s that.

He started telling me to “hop off his sack already with the phone” well.. 2 months ago when he was outside drinking (when I didn’t have a problem & I would actually fall asleep not caring what time he came to bed) he walked in at 2am stumbling woke me up and told me there was someone else. He’s worked on his drinking, it’s been one hell of a ride coming back from that he swears up and down he doesn’t know why he said that and he apologized. So now when he’s drinking outside with his phone, it triggers me.

I’m genuinely asking if I’m the problem, do you ask your s/o what they do on their phone? How can I stop? How can I get better?

This morning we woke up and he said “are you still going to be in a mood?” And long story short I told him “I’ll hop off” he replies “omg yes please”.

The only times I can careless is when I actually care-less.
