How to stop thinking about his ex

Hey girls,

So I just saw pictures of my bf’s ex (first ever) despite the fact that he has many of them.. but obviously he doesn’t follow them on ig and we don’t talk about them individually. This is my first relationship and I cannot really deal with the fact that his French ex is kinda hot. Much taller than me, great body, really nice boobs. Well I didn’t expect this so I can’t stop comparing myself to her.

He saw my face and started comforting me that I can’t compare myself to her that I am way beyond her in all aspects and he has never loved anyone like me.

Lmao tho I already have self esteem issues and despite him telling me this, I just can’t stop thinking about the way I look (I gained weight in quarantine, have huge boobs so they are a but saggy and asymmetric..) 🥲😅 silly me. Any advice on how to stop thinking about this? It just ruined my day.
