of course he's 'into' his "good friend"! Many of us are into our 'good friends' of the opposite sex Big Time, and will even be very chipper and upbeat when we talk with them! I would love to see all my friends who live far away, on Skype! It's healthy to have good friends of all ages and both sexes and so on...at times you feel 'a line' is being crossed you gotta work out where the insecurity is coming from...because of him? or in yourself?....best to talk about it...all of these feelings are natural...but gotta be discussed if they're gnawing at you....
