I just want to canvas your idea of BDSM (your post #10) and clarify that BDSM occurs between consenting adults. It does not occur in confusion and without consent. If you haven't spoken about it in detail and spoken about clear boundaries when it comes to control and pushing limits, you are not two consenting adults. I don't know how old either of you are also but this not BDSM. I think you have some inclinations towards tolerance for controlling situations which is dangerous if it's not explored in a safe environment between consenting adults. Don't mistake this for acceptable behaviour if it falls into a blurry category or is confusing to you.
He may also be exploring parts of himself that are heavily into fetish and control but he is not doing it in a safe or respectful way where there's a clear understanding between parties. Some of his demands were so left field that I did also think it was fetish-based (minor in their request, high level demand in their tone). I'm referring specifically for example to his request for photos every day or else kind of tone which (if isolated) sounds quite ridiculous. Take a breather, put things in perspective and try and evaluate whether there are clear understandings between the both of you. If you are perpetually confused, this is not a healthy situation for you.
