The right move?

How do you know when you made a right decision? How do you know that you did the right thing? Your heart was saying yes, but your head was just terrified. You meet someone. There is an instant spark.. You feel as though you and this person have known each other for years. You seem to be getting along great and the sexual compatibility is all there. You think to yourself, good job. We are gonna work out, just take it slow and don't cling. Then comes Saturday night, where you resent the way you felt because for almost a entire week he has said nothing to you. You feel used and mistreated. You feel like why would I bother with all the mushy stuff with this person if it wasn't going to work out? Why hasn't he called or texted? The real answer is I don't know. Lots of people get wrapped up into their own lives that it makes it almost impossible to have time for another. I either really gauged it wrong, or misread how he was feeling. There may still be hope, but there is just something off. I guess I just have to move on and work through it. Maybe he will come around, maybe not. Sigh* Finding a mate sucks sometimes. :(
