Ok, I've read your story and I guess I can understand the whole things.
First off all, he is a player, I just curious that he has a new car then he probably has a job. Well, plus he has a look, money, and gfs. He seems to have everything now. Look, he broke up with you and tried to date your friend. That's not actually normal, but that is not really special at all, but what happens if a guy does that? There is only one answer for that question. "player", Player is the only question, I think you know it more than I do so you decide it if he is a player or not."stop reading and leave yourself for 15seconds to think about it"
I have a question, does a girl know that you were his gf? I guess she does right? Look, she knows it but she still wants to date him and this is showing alot. That girl has been in loved with him for a long time and now she has a chance when you both broke up. There is no way he can date her in just only 1 week besides she knows that you and him were in loved. Well, I think you should give up I know its hard to do but if you don't try it then you keep staying like this forever and keep having sex with him in his car or his house instead. And later you realize that he is not your bf, but your friend's boy friend! But that's too late because you had been wasting a lot of your time over a guy who already have a new gf. Remember time can't go back. However, it's not too late. STUMBLE OUT RIGHT NOW! There are a lot of boys in this world, some grow up, some move on, some singles, and some still alive! You don't have to be like this. Don't be afraid of losing a toy. Boys are toys for girl just thinking it. I'm a boy too and I think if a girl thinks that I respect her more because at least she knows that boys are not as value as something is called value. "BOY ARE TOYS! Remember no one would think your dumb if you decide to move on, but everyone would think it if you choose staying!
Think about it.
