I noticed that the girls I talk to end up flirting with me more and constantly texting me when I demand them to do things and call them on their bs. With that in mind I stumbled across this section of Reddit and I need your help on how to change.

Looking on my past messages I used to constantly be ok with taking shit from girls and always kissing their asses trying to be that cute little "sensitive guy" when in reality I was being a bitch and after getting no where I have decided to change. So how do I do it? Where do I start and what do I need to read/know before hand?
