Did my boyfriend violate my privacy when he removed a picture of me and my adult child in my home?

My boyfriend tends to be overzealous sometimes about including him in almost everything even when it’s not particularly appropriate. He sometimes gets angry about this but typically is somewhat understanding. Recently, I was away with my children and he asked me whether it was OK if he came to my house and use my pool and grill in my absence. I said it was OK and he did come over. In the past there’s been a lot of tension between one of my adult children and my boyfriend. Also, we had a big fight recently (not about my kid but about him lying to me) and because me and my kids were going through a very close friend/relative dying (and she died a few days before we went away), I decided it was best if my bf didn't join us the whole time so I invited him for the last 2 days when it was just me and my other child (who doesn't have a big issue with him). He was really pissed and insisted on still coming for the last 2 days and didn't stop complaining about the fact that he "wasted" 3 days of vacation, etc. and spent money on a hotel the first night he was there, even though he could have worked if he wanted to and even though I was paying for the vacation home myself. Frankly, I couldn't cope with him the whole time.

Sometimes when this particular child visits me I do put away a picture I sometimes leave out of me and my boyfriend. I did this recently because we were all upset about losing our family friend and when I returned to my house after my boyfriend using my home I noticed that he put a picture of me and my adult child which was in my bedroom and into one of my drawers face down. Did my boyfriend go too far since this is my house and he doesn’t even live here? I know the message he is sending but is this really beyond being appropriate?
