Something really interesting has happened to me right now. I'm a guy with a really arrogant behaviour and let's say I have some bad boy traits (I use more push than pull during conversations)

I often read here on TRP that women like bad-boys because they believe they have a "nice side", and that they are not like they seem to be.

I was talking with a girl which is really feminine (she literally acts like a 5 year old girl) and the conversation was something like this:

Girl: You should start being more nice with me Me: If you want to find my nice side you will have to dig really deep, and it will take you a lot of time. Girl: I have all the time I need, and stop being so cocky because I know you are not like that :$

I don't know if I should have told her something like "This is my behaviour, accept it or bye" instead of what I said. I felt like I had to open myself just a little bit, like giving her an opportunity to know me better.

I was curious if that women's fantasy about the "good" bad boy was real. And it actually is.

The thing is, I hate when women try to betafy me. It seems like my mother telling me "honey come her and hug me", and it's so "gay" to me. I hate being nice due to past experiences which ended up really bad. I can tell i've become emotionless and I have no feminine traits (probably due to high testosterone gained through lifting and diet).

Should I open myself to her or remain a strong emotionless rock?
