From happy to scared

Yesterday I skyped with An. I really enjoy our chatting time. We don't often do it anymore (my fault), but the times we do its absolutely wonderful...Every time we talk, I always find myself voicing some of my fears out loud. I don't usually do that, but with him it just happens. Although they are still specif topics that I never mentioned to him before...Those topics are hard for me to even bring up...and yet I find myself Wanting to tell him...I guess you could say im scared. Scared of what? I'm not entirely sure. I know he won't make any rude comments...but the idea of telling him (or anyone else for that matter) is scary....
