My ex and I share a daughter. We've been broken up for years and both have since then remarried. My daughter has a pretty good relationship with her stepmother and even calls her her other mom. Since last year, my ex and his wife have been having some real struggles. I've tried to keep my nose out of it, but there constant arguing is starting to affect my child. She spends the weekends with him and sometimes comes back very upset because they treat each other badly. Part of me wants to speak to him, at least to tell him to be more mindful of how and when he chooses to unleash his wrath against his wife. From what I understand, he even tries to put my daughter against his wife and what not. I just don't appreciate my child being put in the middle of this. Should I speak up?
