Advice...

So my bf and I have lived together for over a year now and I try so hard sometimes to get his attention when I wanna have sex or just for him to notice me at times and recently I’ve been going through depression and I literally feel like my life sucks sometimes and sex is the only way that I get distracted and makes me feel good but he rarely wants to have sex and he brags to his friends about all the porn he has bookmarked on his phone which is over 50 videos. That really made me feel so worthless like I’m not even that good for him, idk what to do that literally just broke me more.

(Since going through my depression I’ve gained weight and I’ve gotten stretch marks in places that aren’t attractive or cute at all which I feel like is the reason he’s turned off or just doesn’t wanna have sex with me)
