What is the not crazy thing to do

How do you know if you should break up with someone if they have you so scared to ask whats wrong? They say ur Being weird or paranoid.

Communication is essential in a relationship and, if I am understanding you correctly, your partner instead of communicating what is wrong says you are being paranoid then they obviously either have something to hide or do not know how to communicate what their feeling. You need to sit her/him down and let them know you care and want to be open and honest with each other. If your partner continues to avoid you by accusing you of being paranoid or weird then it is time to move on because you will never be able to communicate properly and that will only lead to problems and misunderstandings. Unless, of coarse, you are the type that thinks something is always wrong because someone is quite or not in a great mood, etc.
