I have the urge to make someone feel special but then immediately find someone else.
Why would  you want to lead someone on only to immediately leave them?
It makes me happy to have someone interested in me.
Of course having others interested in you feels good, but it's awful to lead someone on. Being emotionally manipulative for your own gain is cruel and you could really hurt someone.
I just want someone to like me.
I understand that, but in the end no one's going like you when you do this. The best thing for you do is find one single romantic partner and stick with that.
