I like you because you like me.
I've had a lot of relationships and I am ALWAYS more attracted to men when I know they are attracted to me. Experts (that's me) say that four times out of five you will be more likely to consider dating a man you hadn't thought about previously when you know he is attracted to you.
You know, there must be something amazing about him if he is smart enough to realize that you are amazing!
This even applies outside of romantical relationships. Don't you favor the nephew or niece that loves you most? Don't you like the friends more who make an effort to be around you, basking in the glow of your awesomeness?
We are selfish little scalawags, aren't we? :-)
