DH has a hobby who goes to three days a week when the children are at nursery. Today he said he wants to add a Sunday as more people attend on weekends it's more social. However, I think this is excessive and meant I am left with both children half of the day. Which should be fine if it's unavoidable, or it's the only day he can do it. I said as much and he thinks IABU as he does look after the children between nursery and my return home (which is always in time for bath and bed) from work the one/two days I work from office. I feel that I can't avoid commuting time but he can avoid a fourth day for a hobby and not sacrifice family time as the weekends are the only time all of us spend meaningful time together. He's sulking now and not talking to me. AIBU?
