I suspect I'm BU (please don't flame me!!), and would welcome some perspectives.
Am on maternity leave with 8 month old DC (only child). DH works full time Monday-Friday, often comes home in time for bath and bedtime with our DC. Every month he'll spend maybe 4 weekend days in total (sometimes half day, sometimes full days) pursuing a hobby (to say more would be outing), which takes him out of the house and leaves me looking after DC. He does the same on some weekday evenings once DC is in bed.
Recently we had a chat as I have started to resent looking after DC by myself on weekend days in addition to weekdays (I should add that grandparents live too far away to help with any regularity). I acknowledged that maybe IABU about it, and he said he did feel I was being unfair to him - he works hard during the week, spends 75% of his spare time at home helping with DC/household stuff, and already barely has time to pursue his hobby to the level that he wishes (which has been really affecting his mood).
While occasionally I leave DC with DH for a few hours during the weekend, I don't actually want/need a 'tit for tat' arrangement either.
AIBU to feel a bit resentful and actually quite envious that he is spending time on his hobby while I wish he would spend more time at home helping out with DC and hanging out with us?
