My partner left me and my now 9 month old son just after Christmas. Over his short life, my ex has bothered very little with my DS yet since he left, he's playing the injured father act, I don't let him see his son, etc etc. Which is not the case, I just want arrangements to suit DS schedule. Last week he messaged to say he couldn't pick him up as arranged because he was going on a night out the evening before and wouldn't be able to drive in the morning as he'd be over the limit. I said he could pick him up towards lunch time and he said this still wouldn't be suitable. I suggested he act like every other responsible parent and go to bed at a time which would allow him to look after his son as arranged. This was no good either, because I didn't understand that it was a big night out and once he's there he wont leave etc. Now I get a message to say that he can't have DS next week either because he's on a lads night the night before, so his parents will take him. I feel so bloody angry. He has him one afternoon a week and he can't be arsed prioritising his child over nights out. I would be less angry if he wasn't telling everyone he comes across just how much I'm restricting access. AIBU?
