I've noticed this happens with a lot of the women I've had a crush on. I meet them somewhere (school, party) , but a few weeks/months I start getting closer with them and eventually crushing on them, but they don't feel the same way, possibly because a lot of time has passed and they know me well enough to know that I am not their type, but at the same time they don't know me that much.

The last woman thatvI met, I tried to to waste the least time possible and start getting closer with her asap. And it so happened that she's my girlfriend now.
