Ok, NC for this in case I'm being an idiot and VU.
So, exDH and I separated. We have one DS. Both work full time and son goes to a childminder. He has him one night in the week, and one day at the weekend. It alternates, and it works. Generally all is amicable.
Yesterday he called to tell me that he's going to Aus in 2 weeks to see his friend for 2 weeks. He then proceeded to tell me that he was going to go in 4 days time but his sister has told him that he should give me more notice. So he's generously given me 2 weeks instead. He's not checked the dates with me, he's just told me it's happening as he needs a holiday.
Now whilst I couldn't give two hoots what he does in his time, I'm a little annoyed that he's just assumed I'll look after our son and have no plans. Of course I'll do it, he's my son and I love our time together. What I'm annoyed about is his ability to be able to what he wants, when he wants, with no thought or consideration for anyone else.
I've not said anything to him, I really cba. But AIBU to think he's a bit of a twunt?!
