To compromise, sacrifice, or support no matter what

When it comes to relationships, I think it's best to support the other person as much as possible. The trick is doing so while you disagree with what they're doing. Choosing to instead reject or deny what they want to do for themselves could lead to tension and changes of behavior you may not like. Is it best to sacrifice who you are for them? Or can you reach a compromise? Sometimes even supporting someone you love isn't enough.
