I don't like to compare my insides to other people's outsides. I don't think that if some other wife has stayed it's because she loved her husband more than I do if I leave my husband. Maybe those other wives didn't have the courage to go? Maybe they didn't have the strength to support themselves and didn't think they could manage without their husband's money?
I love my husband dearly, but there may come a day when enough is enough. When it's there, I hope I'm stable enough to know that it had NOTHING to do with how much I loved him. Being a doormat is not loving. Pity is not love. Caretaking/enabling is not love.
Again, I will not allow myself to compare my insides to other's outsides. I can't read minds so I will not assume to know everything that goes on in other's relationships.
