I think IANBU and he only sent them to make a point but happy to be told otherwise.
On holiday when DS birthday this week. Spoke to him about it long before booking, no issues for him, gets money for birthday and apparently going out with mates as reaching 18, didn't want party or fuss, not his style.
Anyway, on said Birthday get two picture messages from exh showing him, his current girlfriend and both DS. No concern from me that he has taken them out for DS2 birthday, but why include him and his girlfriend? Does he want me to react? Is he trying for a guilt trip that I wasn't there?
Needless to say I haven't responded and I wish I could block him but DS1 has mental health issues which we need to correspond on.
Sorry, rant over!!
