Yeah, that would be cool to tell him about how you wanted to contact him and then his email fell in your lap!
This post of yours is a few days old so I'm thinking that you may have already told him you feel connected with him...? I don't see any problem with that! naw....I mean, it's the Truth...and if he feels weird about it then he feels weird about it! (that's his problem! ha) If he's leaving in July...then I can understand the feeling of pressure. Is his girlfriend actually going with him or are they just casual?
Follow your heart, Abalina...it will lead you where you need to go.
I fell in love with one of my boyfriends about 6 weeks before he went to Europe for one year...but we knew we couldn't be apart so I visited him there twice in that year and then he came home....so, that he's leaving doesn't mean a thing!
Be open and honest and listen to your intuition....
