It sounds like she's adding pictures here as a tit for tat thing, something that's never good in a relationship. She's jumped from one manipulating behaviour to another, and that's what she's going to do whenever she can't get her own way. You should talk to her and tell her you love her, but that any partners need a separate part of their life as well as the life they share, and that if she can't accept that then you'll have to part. You seem to be coping ok with this behaviour now but imagine 20 years of it, and it will escalate because every time you accept it you give her permission to do it. Tell her firmly you joined this site, she was happy for you to join it and you're getting up to no wrong here, just enjoying chatting and finding some support. If she can't accept that you need some areas of your life where she isn't involved then you're right she's a controlling bitch and if you let her control you in this after being so successful at getting her own way in this she'll move on to another area until you don't have any control over your own life.
