Been with DP for 5 years and living together for 4, so he's a step parent to my DC for all intents and purposes. They have a very good and close relationship most of the time.
DP is going off on a jolly on DC's birthday for a few days. It's an annual event DP has wanted to do for a while, but didn't go last year due to a) being in debt and b) because I was studying for my finals at the time and needed DP's practical support at home.
I feel hurt by the fact DP will miss DC's birthday, as I know it's not something DP would ever do if it was HIS DC. But then that's the point I suppose, DC isn't DP's.
Would this have upset you as a step child? Or am I thinking too much into their relationship and the message this will send to DC (to me it says: you're not that important to me).
