Name changed as am paranoid user name will identify me in RL!
H walked out about 6 months ago - total shock. Since then we have tried to keep lots of contact with him & our two young DC's. I feel very angry at him and am not in a great place so may be being unreasonable. ;)
I am training for a triathlon - only have the opportunity to train 3 times a week when dc's are with him. Today he casually mentioned he couldnt make the next scheduled date (2 days time) as he is on a night out. I said he should be responsible for finding covering childcare while I was training (about an hour). AIBU? He is making out like I really am.
