This isn't AIBU because I know I'm not being unreasonable but I was a fool for believing he would help me out.
ExDH was broke over Christmas ended up with no electricity in the meter etc etc so I loaned him money and gave him the repayment terms (not a lot, less than 100 euro so 50 euro per week for two weeks) even sent him food when he took the kids for access last night because he has no money until tomorrow. I picked the kids up this morning for school and asked him 'can you do me a favour on Saturday and pick them up for access early' (he usually picks them up for 12.30 and I asked him to do 10am instead as I'm visiting a friend down the country for the weekend and wanted to get on the road) and he was like 'ah no I don't think I can do that early sure I'll need a lie on.'
I'm ripping that I even asked him now.
