I can't be cool

[Zhukov]

When I first meet a girl I can pretty much be smooth and make them laugh for the first few weeks, but after a while this wears off and I just turn into a nonce.

No matter how hard I try I can't seem to be cool around girls I like for more than a few weeks. This in turn makes me more depresed and boring to be around.

I honestly don't think it is from being nervous.

Does anybody else have a similar sort of problem?
