We met when we were very young. I'm very shy at the time.. but I liked him a lot, he lives near my house. But now we don't talk anymore. We never talked for many years. But the feeling never went away.. I still like him a lot. But he already has a girlfriend. And I don't want to ruin their relationship. I just want to confess that I like him just to let him know and to finish what I didn't get to do 8 years back. It's stupid I know, but I just want to get this done with.Is it crazy to do this after so many years?

You shouldn't have waited so long. Unfortunately he has a girlfriend now, and it would be selfish to confess to him. Looks like you may have to wait some more.

How about going out and trying to meet other people? Instead of devoting your feelings to a man that is already taken.
