Wow...I actually read the whole thing and can say I too have been in that position...all of them.  I've also been in the position of fully taken advantage of for my computer skills.  Well adter my first date with my now wife I threw all of those previous "friendships" went out the door.  I got a new phone number and moved and no one knew what happened to me and I'm sure all their computers got thrown out from too much virii hehehe.

Anyhow stay positive..  It took me until I was 27 until the right girl came back in my life!  And before her it was about 3 or 4 years of no girlfriends for me. :-/
