y’all help!!! this is possible triggering content as it involves i guess cheating??? i’m not really sure :/

back story first: i (f20) have been with my bf (m22) for almost a year now, our anniversary is on valentine’s day. i have huge trust issues obviously so sometimes when i think something is up i’ll try n sneak thru his phone while he’s sleeping to see what’s up yk? well i’ve never found anything before until i looked at his recent history on reddit… he’s never really used it before but i think that i might have influenced that bcz i use it a lot, and am part of some nsfw groups with p0rn, which he knows and has told me he is ok with bcz im hypersexual and he isn’t. anyways, a few days ago i noticed he’s been looking at mostly gay male stuff at first, and now looking again it’s been refreshed and he’s looked at other stuff since then. i’ve told him i don’t like porn and on top of that his sex game hasn’t been the greatest lately, which isn’t normal and he hasn’t been having it with me as often either… he works all day (10 hours) bcz he’s a tow truck driver so i’m scared he’s been getting off to these at work and not saying anything about it and then just “pretending” he’s tired when he gets home idfk i just know that i’m spiraling and have no fucking clue what to do. we live together and i can’t go anywhere especially since i’m a stay at home gf bcz of physical health issues i have so i can’t work out high means i’m living off limited finances 1400-2000 a month and i don’t think that’s enough to live alone 😭 advice…?
