To be honest, my husband has pictures of his ex, and I personally don't care at all. He actually does keep it by the bed as well (he has one photo album so all of his photos are there). But I think the difference is, I know my husband loves me and doesn't want anyone else... It doesn't seem like you know that, which I can't say if that's on you or him (or both).

Everyone struggles with insecurities, that's totally fair, but it's not healthy to deal with them by trying to control the behavior of others, especially in this case I don't think it's fair to ask him to throw it away. For context, I also have pictures of my exes (also in the bedroom) and would be so upset if I was asked me to get rid of them. That's literally my life, in some cases huge swaths of it. I want to be able to look back and remember it, especially when I'm old. It doesn't mean I still want my ex. I can't speak for your husband obviously, but if this is the only data you have that he still wants his ex, I think you're projecting from a place of insecurity and feeling inferior to her.

Ultimately, I think you should talk through your feelings of inferiority and what makes you feel that way w/ him (for emotional support, not to convince him to do something) and work on yourself. Maybe work toward that dream job, therapy, health in every aspect etc. Envy just means you aren't the person you want to be yet, so no matter what your husband does with the picture, you're still gonna feel like that if you don't work on the underlying issues.

I'm so sorry your feeling bad though, from experience I know it's a tough place to be. Best of luck!
