We share care about 60/40 to me, but ex quite often needs me to take the dc on his weekends due to gigs (he's a wannabe musician).
This week the dc got back to mine on Weds and told me "We're with you this weekend as dad has a gig." I think that's downright rude - he didn't even ask/tell me, and if I'd been unable to (unlikely) they would have felt messed around. I texted him to clarify and he confirmed it - no please or thank you. Part of me was irritated - I work a lot on his weekend (teacher), but I had nothing social planned and mainly felt pleased to be getting more time with the dc.
So we agreed I'd drop them at his first thing Sat am as usual, he would bring them back to me at 3pm when he leaves fro his gig (in another city) and pick them up 'some time on Sunday morning (this bit is irritating as he won't commit to a time as he wants to see what time he wakes up.) He would then keep them Sunday night (usually brings them back to me at teatime), leaving me time to work on Sunday and saving me having to pay my unofficial childminder on Monday morning.
So I adjusted my plans accordingly - stayed up late chatting with a friend online last night and this morning the dc got up earlier than me and watched tv. Usually when they are going to his I make sure I go to bed early and get up with them to spend a bit of time with them before taking them to his.
Then this morning when I dropped them off he said casually 'Oh, the gig is cancelled now so I'll keep them tonight." I'm pissed off beyond belief and just feel totally messed about by him. I said you could have told me and he said he only knew last night - so if he'd told me immediately I could have adjusted sooner. I was on the spot but asked if we could just keep it as agreed for this weekend. He agreed, but I don't know how happy he is about it. I don't want to antagonise him as our decree nissi has just come and my solicitor is about to send him the financial stuff he has agreed to, so I don't want anything to jeopardise that, but I feel like he totally takes me for granted and thinks nothing of messing me around - and the dc too. He is reliable in the week (thank goodness) but wants his cake and eat it at weekends.
If he rings later and tries to insist on keeping them tonight, wibu to say no?
