I think my BF (30M) lacks manners and etiquette

Problem/Goal: I found out that my BF (32 M) was wearing a sleeping mask during a virtual meeting with the remote company we're working for. I'm considering to breakup with him.

Context: I'm a little younger than my BF, and I sometimes feel more mature in terms of manners and good etiquette. I know I don't have to judge a person about that, but this time it's different. I knew it's very obvious that someone will look informal wearing a sleeping mask headband in a virtual meeting when I saw the meeting recording.

I have this thoughts na parang nauulit lang. In the past I called him out about wearing cap inside the cafe and while eating, his loud sound when eating or slurping, and etc. Ayoko as much as possible mag call out, pero I don't feel at ease seeing him like that. Maybe, because this time I'm the one who referred him to the job.

When I tried to open it up to him, every blame goes to me. Like, I should understand 'cause it's his first time to work on that virtual setup. To me his reasons are not on point, because one time he asked me if it's okay to attend a meeting wearing sando. Of course, I advised him not.

Medyo stubborn siya, and alway telling me na grabe ako magjudge. I may have told him some words that might have hurt him, but I think that's out of care and I always try to talk about it in a nonagressive tone.

I'm considering breakup, coz napapagod na ako eveytime magcall out and makarinig na hindi na uulitin. He has a good side though (he's an acts of service guy who cooks me food when I visit their house, hatid sundo ako), pero etong last discussion namin about sa virtual meeting na yon is not so good. He didn't acknowledge his mistake, instead ako pa yun parang blamed and "bahala raw ako" while I was talking about it (in my gentlest tone).

That's all for now. Just would like to know if somebody here also had this experience.
