Taking the marriage certificate and wedding videos is strange. Are you positive? I guess the certificate doesn't matter - you can always order a replacement one from the registry office if you need it for anything or want to file yourself. The videos are stranger. It seems a weirdly sentimental thing to do. Or perhaps he wanted to you see he'd taken them in order to have some kind of emotional effect on you? Who knows. He probably doesn't know himself. But yes - he might co-own the house with you, but you are entitled to privacy in your bedroom and security in your belongings. Are you going to post your draft email here for feedback before you send it?
