I think you should listen to your gut. If you feel there will be nothing, then you are probably correct. (Been there, Keen.com psychic swore something would come of it and that I can change the outcome.... nothing happened... he cut off all contact with me...)
Don't settle for contact if there won't be a relationship. I, too, have settled for contact and it's just that- CONTACT. For me, it was the early 2000s, when AOL instant messenger was popular- our contact consisted of a brief IM on how to code a website I was making for class. That's all...
Meanwhile, he was in a serious relationship! I had gone through one boyfriend- dating for a few a months. Guess what? While my own relationship was "meh", it was "meh" because I was soooo focused on this other guy!
