Hi, I am not married and I don’t have any kids so my advice might not be the best. But something I have found talking with other kids now adults that were raised in a marriage that was out of convenience rather than love. The kids always know when something is wrong, and it’s easy to harbor resentment when your not feeling heard or not happy in the relationship. Sometimes staying can be more damaging to you and the kid than divorce can be. It’s hard at first on the kid but it usually gets better. And I know it can be hard to not want to hurt your spouse but it’s not your responsibility to make him feel secure or mentally stable. If it’s easier think of what advice you would give your daughter, would you want her to stay in a relationship she wasn’t happy in and was hurting her mental health. My mom and dad fought a lot growing up it triggers ptsd for me now sometimes but my mom always told me if it came down to it she would have chose to protect me rather than my dad (if it wasn’t the best for me to be around that situation). They fixed their problems but my dad had different issues than what your describing. And my mom is most definitely straight. anyways hope that helps -Lauryn
