I don't think Love can be expressed by putting up with someone else's abusive behavior. That's not unconditional love to me; if I love someone, I want them to be the best they can be and being abusive is never that best! Sometimes love is difficult because you have to express yourself! Your anger and fears and disappointment are all part of you and if you love another person unconditionally, to me it means you let them know "you". Because you are angry or disappointed in a person does not mean you do not love unconditionally, God gets angry over and over in the Bible! Jesus rebukes the Pharisees! The rich man whom He loved but who wouldn't give up his riches and follow Him, that was true Unconditional Love in action, insisting the man give up what he had and be someone better!
