Regret marrying my husband

I’m feeling super negative recently towards my husband. Yesterday I asked him to change our 18 month olds nappy he goes no. Then continues to say ‘it’s like you ask me these questions on purpose, to argue because you know I’ll say no’ he doesn’t play with our LO or help with bedtime. He baths our LO but I’m the one who gets LO dressed after bath time. I just feel so sad and upset that I married someone who’s not a hands on dad. He sees it as he works and that’s his job done he will cook sometimes but leaves the kitchen a mess. He just doesn’t help with the kids at all and it’s just really starting to effect how I feel towards him. I feel like a single parent so feel I should just be instead of dealing with all the stress and tension of being in a marriage I’m unhappy in. Guess I just needed to vent!
