How do I let myself trust?

I find it hard to trust guys b/c of a messed up past, even though I think I'm in a trustworthy relationship nowadays. We are actually moving in together soon. How do I let myself trust him?





The 2 things that make it difficult are:





-He told me that he sometimes has fantasies about about other women (celebs, girls posting pics on the internet, but no porn)





-He's ok with the idea of ';flirting'; (although I really don't know how far that goes) with friends, even ex gfs, on IM





I feel kind of uneasy that these things are true, but also glad that he is honest about who he is. I strongly believe he would never cheat on me. All other parts of this relationship are great, the best relationship I've ever had. Can I get past this? Should I?





Thanks!





P.S. Plz don't just say ';at least he's not cheating on you.'; I need more than that in a guyHow do I let myself trust?
guys do like what they see. women like what they feel. get my drift. guys will look, they all do. the flirting thing is not cool though. I would be uncomfortable too about this. let him out on the leash and see if he hangs himself. trust him until he gives you a strong reason not to. just keep your gaurd up though.
