My last GF freaked out and left me because I was flirting with other girls too

. You have no idea how much I laughed at her after that..., and as a side-effect of the laughs, she thinks of me as a total A-hole.
Anyway, I have that player 'problem' too. Alot of people see me as a 'player' and sometimes they even SAY it out loud when I pass them, which isn't really annoying... But just wait when you hear this.
Recently my friends (including both guys and girls) have been gossip-talking about me being a 'player'
behind my back! One of my best mates told me about it and said that I should somehow get rid of the gossip-talk.
So now its been about 2 months since my friend mentioned about the talk me being a 'player', and the situation now is developing in to ALOT WORSE.
For example, some of the girls I know give me discusting looks sometimes out of nowhere, and a HB I just met through my friends responded REALLY GREAT in-person, but then after #closing and me leaving her with some of my friends... She became UNRESPONSIVE AS HELL!
Theres HUGE gossip-talks about ME between my friends! Its so complicated that its even funny

!
Anyway now how to get rid of the problem is to simply state that you are not a 'player', you just think of flirting and being around girls as "how you feel", for example flirting with girls is
fun and really enjoyable for me.
