Wheres the line between arrogance... and confidence?

Lately a girl has been having a go at me every time i come online (to the point i dont even talk to her anymore cause its always the same shit)

Basically her arguement was that im a really mean person and i come off as a big asshole. And im very arrogant.

I really appreciate her telling me this, it makes me think maybe i am and she is the only one to actually tell me? Although lately i have kinda stepped back from Pickup as i use to be really into it last year. But now i cant be bothered as much. I dont think i show of or talk myself up that much.

So where is the difference between arrogance and confidence?

Some people mistake confidence for arrogance...
