I agree with the above, it is common for people with children to go back and fourth, for some it’s an instant “never again” and that’s fine and a lot healthier but it can take a while to get to that point for some and people think putting their own misery aside for the “better of the children” and a family unit is best, often forgetting just because children don’t always see it, doesn’t mean they don’t feel and pick up on the tension and hatred emotionally.
It can be super hard to break the cycle and start a new chapter; especially when that person is all you’ve known, your first love,
your first house, your first child, your first heartbreak. They just need to break the cycle.
