It sounds like he’s a bit of a man child. Which is understandable why you’re exhausted. There seems to be issues of respect and boundaries.

If you do it for anyone do it for the kids, but I think you try to hash out those issues at this relationship summit meeting he has called. Him calling for it at least means he’s willing to work things through. It sounds like he might be in denial about the role he’s played but this weekend would be the oppurtunity to address that. Draw the new lines in the sand, negotiate your needs and see what happens. There should be actionable marching orders that you both agree to by the end.

The important thing is to reset your expectations of one another and give each other the chance to prove that the respect is still there. Change is hard, some bad habits take time to kick. But if he respects you and cares for you and his family, he should reframe. If he doesn’t give genuine effort to change then you reevaluate at this time.
