Just that really!
He's just so negative and miserable at times
He says he's very busy with work but surely that doesn't mean it's fair to our family to be so grumpy.
Every weekend for weeks he's said he feels unwell or tired, but seems fine in the week. I've said perhaps he has an allergy to me and DC 
He takes part in family stuff but sort of halfheartedly. I've raised it with him and he said he's just tired etc. he seems to think not doesn't impact us, but it brings the whole vibe down.
Yesterday he was very busy with work and then came down for dinner with us. In the five minutes I was dishing up he started telling DC off and wrestled iPad off one of them. It just feels so unnecessary. They'd been absolutely fine until he appeared.
This morning DC was bargaining with me in a jovial/semi-whining way, which I was dealing with, and once again he gets involved to say something negative about DC always complaining. I ignored him but think I wonder where they get it from?!
I do absolutely everything for him, DC and the home, and am happy to, but I'm getting tired of being sympathetic to his misery. I know he's busy but we all are, so are millions of other parents. We are A LOT more fortunate than many many people.
I feel at some level he's unhappy with his lot, but it was a joint decision to get married and have children. It's a bit late to change our minds now!
