If apart from me a man is dating other women/girlfriends too. Then how can I become the one and only for him? How should I behave,how do I have to carry myself, behave or etc. so he is more and more driven to me than to the other his girlfriends? Eventually starting to be afraid to loose me, leaving his girlfriends and seeing only me?
Ex players' opinions are very appreciated!

Not a really a player, but I always enjoy women who have self respect enough to not be used or be a back up plan to a man.

I am a guy who likes confident women who aren't afraid to stand up for what they believe in, especially when it comes to how they are treated. You want my advice... quit talking to this guy.

Unless you consider yourself a game, don't let yourself get played!
