I have never felt that way about someone except my children. I love them to the moon and back, but sometimes they are little turds.
When it's come to men, I can understand it to a point, but when women are abused (or men for that matter) and still insist they love their husband, I think it's more the fear and abuse and wishing talking. But that's just me.
I love my husband. He has done some things that have hurt me but I still liked him and still loved him. I understood his actions and accept that this is just life...ebbs and flows. He's never been abusive. I had an abusive ex and I didn't love him, or like him.
