Um...

It sounds to me like your boyfriend is very insecure and he attempts to control you by expressing his insecurity.

Kind of a 'if you love me then you will make me feel better' thing to do...

Is he in therapy?

I'm just thinking that maybe you guys could benefit from some kind of couples councelling or something? Sounds like he could benefit from individual therapy too...

Your pictures are your pictures. I don't think that it is fair of your boyfriend to expect you to throw away or forget part of your life. It is part of your life. Part of your experiences in life. If he doesn't like it then he doesn't have to look at them...

He needs to learn to control his upset and frustration when he doesn't get his own way. So that he can be a better partner to you methinks...

I'm a bit concerned because it does sound like he has the potential to be controlling...
