AIBU to consider leaving husband for kids

[HW89]

First post so please be nice I just need advise!!
DH is step to 2 eldest who are 8&9 and we have another together who is 1. Together for over 7yrs but I hate how strict he is, not just older 2 but all of them. If they leave rubbish from sweets on table, grounded for a week, if they leave empty glasses then they have to hand wash them. I love him dearly, but we parent differently. Kids are kids surely? It’s our job to pick up their bits? Kids are in resentment mode and it’s causing problems. Different upbringings, as a child he had to do lots of chores, I never touched a thing as my parents did it for me. Maybe I’m just spoilt and I’m enforcing this on my kids?

OP my son is 8. If he refused to pick up after himself. I would probably end up grounding him as well.

As it stands he always puts his plate in the sink and wash it if there arent any other pots. Hand washing a glass you use, at 8/9 isnt ridiculous. We dont have a dishwasher, so everything is hand washed.

Thinking of leaving your relationship, because he wont pick up after the kids and is teaching them responsibility. Is a huge jump?
