My ego doesn't let me be romantic

I'm not the typical asshole. I smile to people, I'm funny but I'm mean, selfish, careless, judgmental and above all I have a dangerously high amount of ego. I'm good looking + intellectually gifted which I think justifies my ego.

I don't reply to a girl's messages fast if she doesn't reply me fast. I'm an expressionless prick and i never use smileys while chatting. Not even the :p smiley which helps you to sound less serious. When a girl gets angry at me or when stops talking to me I feel zero sadness.

You can see I'm not very good at game. average success. Yesterday I met my good friend who's experienced and has good game. He wanted me to speak romantically with girls who were interested in me but never reached that level where they start taking sexual.

There were 2 such girls online that moment. I started chatting with them and followed his instructions. Added smileys, talked playfully. Total success. They reacted like they were always waiting for me to talk like that. They got comfortable with me.

Good but as person who strongly believes in the 'be yourself' thing I got demotivated enough to consider stopping the game. I have to be someone else to get girls. I'm not ready to change myself. Trying to defend my ego I've lost a couple of good job opportunities, my place in the cricket team (I'm good at most hand-eye coordination based sports. Yeah fuels my ego even more). So I'm fine with losing women for my ego.

I'm posting this to see whether some other asshole has a hack that could fix my problem. Or who knows there could be a version of game that I can do without changing myself.

TL;DR: asshole with superiority "complex" has problems at being romantic + making girls feel comfortable. Should I stop the game?
