Title says it all, but basically I’ve been dating the most amazing guy for about 5 months. During that time, though, I’ve had extreme problems with comparing myself to his ex girlfriend. It’s had very bad effects on my mental health, to the point where I cry often because I feel like she was hotter/simply better than me. I feel like I should break up with him because of (a) the effect this is having on my mental health and (b) the fact that it isn’t fair to him. I’ve tried deleting social media and redirecting my thoughts whenever I started to compare myself, but it hasn’t really worked. He has done his best to reassure me but it hasnt helped at all. I’ve always been really happy with the way I look/myself, and always thought I was really confident, but I guess not. Advice? And like what should I even say when I break up with him?

TLdr: the title
