Am I just being stupid here?

I need advice on whether I am being stupid or not here.

I think my boyfriend wants his ex back. We have been together for 6 years nearly and I don’t think he can get his ex out of his mind. He has some pictures of her on a memory stick, which I have found out he has been viewing on the Saturdays which I am at work. It breaks my heart so much to see this and to know that I mean so little to him, even after all this time.

I questioned him about it and he said he hasn’t been looking at it. I told him I know he has, and he said I can know all I want, but he hasn’t. I told him that all I want is for him to be happy and I would help him get back with her if this is his wish. He looked at me like I’m stupid and said he would never get back with anyone, which I took to mean that he does want her back, he just doesn’t believe in going back.

I do suffer with anxiety and BPD, so please say what you think.
