I am not a very social person. I am 18 and have had two best friends. The first one was my best friend for nine years and I trusted her well, until I found out that she was intensely manipulative and self centered. after that I had another best friend for two years which I thought was a great person, and totally sane compared to others I knew, but then she admitted to me that she had been lying to me the whole entire time and I realised also that she had big personality issues, i.e. she copied people because she didn't have a personality. I am in a relationship now with a wonderful boyfriend but my past friendships have put a severe dent in my ability to trust. When ever he tries to tell me something I interrogate him and want him to prove his point with evidence because I want to trust him and want to make sure that every time he tells me something he's being honest. Needless to say this bothers him and me intensely. My past friendships have built into me a fear that anyone, no matter how good or loving or perfect they seem, could turn out to hurt me horribly. Is there anything I can do to get rid of this irrational worry?
