That's so sad, but this is how so many women - especially the older generation ones - continue to think. At the end, he will return to me. Women are taught - conditioned - to be nurturers, and we need to care for others while ignoring "faults". People will still judge you by how good a mom, wife, daughter, etc. you are. You are defined by relationships where men can just be men.
Marriage is a partnership of 50-50, if you have to give more to it to work, end it. You cannot do anything that is so wrong that it equates to being abused - there is absolutely no justification. You leave him/her if it happens, it ain't love. It's just sad.
