It seems to me that B has trust issues that he needs to work on before he should be in a new r. Being afraid to admit feelings is not healthy either. It is easy to say that all you want to do is spend some time together without anything serious but two years later you seem to want more and he is unable to give it to you because he has not worked on his own issues.Until he is ready to work on what he needs to be healthy I am not sure dbing will help or is even a good idea.
