Ingridave2 had a good point. Relationships are so subjective. Its really a judgment call. We are also likely to misread actions, and words, of others because we are all so different. You may think someone cares for you more than they really do and end up hurt and disappointed, or you may not see how much someone really does care and end up hurting them.

Communication in any relationship is hard but irreplacable. If you are not sure why someone is acting in a certain way, ask them about it. If you think they are treating you in a way you don't like, tell them. Guessing and making assumptions just leads to heartache. Either yours or theirs, or both.
