Gareth - I'm sorry for this outcome. I could never understand it but online dating comes with this expectation that people are shopping. This means they see multiple people at the same time with the hope of pursuing one. Looks like that's what happened. The problem I have with that model is that you can't plan out ahead and give someone hope that you are more invested in the process than you actually are. Perhaps, these are lessons you learn along the way. But now that you've had the breakthrough, you will be wiser next time around. Keep the faith!
