Only the mods can “close” a question on Fluther. Until then, it’s an open forum.
So many problems in relationships happen when one person has stronger feelings than the other. That root problem creates insecurity, because you start to see every other woman as a potential threat to your relationship. If he still has pictures of them, he might still have feelings for them, and that could mean he’ll be less invested in you.
It’s kind of a self-feeding cycle. The jealous/insecure one nags and pesters their partner, driving them away even more. I’ve been on both sides of this. When you’re the insecure, jealous one, it just comes from reeeeally wanting to be with your partner, as often and as much as you can, the emotional high you get from them, and the nagging feeling that they’re not as invested as you are. When you’re the avoiding one, it feels like you’re dating this nagging, overbearing hellbeast and you just want them to leave them alone.
Being in either position is frustrating and painful. It seems clear that your boyfriend isn’t going to budge on keeping these pictures, and he doesn’t really care whether it’s disrespectful. I can’t make a decision for you. If him keeping the pictures is something you can live with, then dropping the subject is probably the only way to make peace in your relationship. If it’s something you can’t live with, you may need to end the relationship. You can’t always have everything you want.
But sometimes, backing off can be the best answer. If you really want to be with him that badly, you might want to give him some space for a little while. Spend some time without the boyfriend, with other people who care about you, doing things that make you happy, and talk to each other once you’ve both had some time and perspective, calmly and rationally.
Also, I agree with everything @Kardamom has said and I think she is genuinely trying to help you. A lot of times the right answers are the ones you don’t want to hear. If what you were doing was working, you wouldn’t need to ask us for advice… right?
