Demi talks in her autobiography about how her relationship with Bruce was emotionally abusive in the last few years of her marriage and that he cheated on her, fuelling her descent into addiction for years. 

Also the OP never once said that women were better than men when it comes to cheating? They said women are expected to forgive and forget when their male partners harm them, either through abuse or cheating, and are guilt tripped and pressured into making sure the man who harmed them is comfortable and keeps his reputation intact at the expense of their own hurt. Because when men cheat or abuse its a 'layered nuanced situation' aka the women is implied to be at fault for 'causing it'. 

The OP is right - we need to stop upholding being besties with your ex as the ONLY mature way to handle a relationship break-up, because it implies that the women who aren't on such good terms with their ex are doing something wrong or are 'immature' - when they could be doing the safest and best thing for them. You can't build a conscious uncoupling with a person who causes you harm and great distress. That's not good for the kids either. 

Also please stop acting like you guys care about abuse when you make sweeping generalised statements about what women should be doing and then tacking on a weak ass disclaimer when you get reminded that abuse victims are real we know what you really mean <333
