Trust issues

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?

I wouldn't say that your trust issues are completely irrational. You have been hurt by others that you trusted with deep, emotional issues that are dear to your heart. That hurts!

While your bf seems very understanding and trustworthy in some ways, it takes time to build healthy relationships. Especially after we've been hurt. That is part of growing up, really. Realizing that we can't always trust those that we feel/felt safe with is a sad reality of life. We have to be more careful with what we decide to share with others; we also have to take things more slowly before we really open up. Some friends are okay to shoot the sh** with and others can be trusted with more intimate details of our lives. It's a very individual thing. There is no easy answer. Just a reality that we all have to accept at some time in our lives.

Gentle hugs to you...you aren't being irrational imo. It takes time to build trust in relationships. Try not to pressure yourself to automatically trust those who haven't hurt you. Trust is an aspect of relationships that is built ~ not automatically given.
