What's going on?!

Ive had to put up with all of that sort of stuff my STBX has put on his and I think he's kept it public intentionally becuase he expects me to look at it. Photos of days out and bragging about things he has bought with his new g/f. Hes currently on a long haul holiday with her the- third in 3 years. I asked if he'd go halves on a big expenditure but much needed item for our eldest son for school and was told a big fat 'no'. Saying I have to be responsible for it as I wanted to be a single parent and ive got to do it on my own. Even though he has tried to use every CSA rule to get his maintenance reduced (unsuccessfully). It makes me so angry at times I could scream too.

I very rarely go on there, and I certainly don't look at his site any more. Only, if (and its a big IF) there is something specific I'm trying to find out and use as evidence. Lo and behold its usually on there. I found it was playing with my emotions too much, especially when what used to be mutual friends were giving him the thumbs up about things etc etc, and they knew about what went on behind closed doors (people can be so two faced). I limit my visits, usually i have a specific reason, get what i'm looking for and come away again until I think its necessary to have a look again.
