Since he’s not all on board for a second child 100% then I think you really need to take a step back and look at the overall situation.

If he’s already not helping with daily chores it’s doubtful he will want to deal with another child to raise and more mess to clean up.

I know this put you in a tough situation. You want, him not all the way in.

Is couples counseling something he might agree too ?? The unbalanced household chore issues really needs ironed out, things like that just cause more and more resentment as time moves along.

Do you have a Therapist of your own to help you process things with? If not I’d definitely advise you find one.

I wish you luck
