***Any help is greatly appreciated. I'm pretty lost***

We just broke up not long ago. I did everything for her and she said she loves me but not IN love with me anymore. I'm not trying to win her back, but I do not want to see her if we are done. We are the same city league volleyball team and we take it pretty seriously. Ha. I would consider not playing if it meant not seeing her. I know I'll see her out at the local bars in our small town, but I'd rather not see her often. She is very attractive and is a pretty big slut when she doesn't have a boyfriend and I know if I saw her, even at our volleyball games, she would have a dude with her. It makes me sick to think about. I have been out of the game for over a year since we have been dating. I know the main way to get over her is to find someone else, but I have no confidence nor motivation to go out to a bar or wherever and talk to girls.

1) Do I quit the volleyball team?
2) How do I quit being a pussy and being so "hurt" and start talking to girls again? Bc I'm just in the weird state where I don't think any girls would want me (which is my first mistake I know, but Im just being honest). So I don't have confidence after all the shit my ex put me through. (I used to be confident, I'm not ugly and have slept with 18 or 19 women now. A decent amount.) I just thought this girl was the one, and literally she walked all over me. She cheated on me twice, put me in jail for telling the cops that I hit her, let me spend every penny I earn on her, and still has the nerve to say she's not IN love with me. Maybe I'm too depressed to go out, maybe I don't think any girl would want me because I don't think I'm good enough anymore. I don't know what it is.

This happens to me all the time. Don't quit immediately and try to maintain a friendship with her. (who knows maybe she has cool friends). However if she continues being a dirty iceburg maybe you should go with the old movie cliche of cracking a beer sitting on the couch and watch some tv to clear your mind. then drop her uselessness. That movie cliche works for me but it's all about finding your happiness to weed out the negativity.

Thanks for trying, but I didn't feel like that helped me too much.

I think what I was trying to say was to find a relaxing way to rid your mind of those dragging thoughts of her. It may take some time but don't clam up and loose the potential to be happy.
My friend is going through the same problem but he is moping about costing happiness not only to himself but to all of our roommates. Remember the key to what you need will find you eventually... Look at me talking like a fortune cookie
If this doesn't help I'm out of ideas.

i used to be hopelessly in love with a girl, difference being she wouldn't look at me for one second which more than ever made me chase after her (i always get pumped up when i hear i can't have something but maybe that's just me) but in your case i'm not sure what can you do to remedy things in this moment except keep in mind that it's just a phase and that it will pass (eventually).
Also, if your feelings are very strong (whatever they might be) it helps to do ross jeffries's trick for "not burning your circuits" (i'm not sure where you get it but it involves thinking in a certain way about your feelings which is:
1. figure out what your feelings are and doing that is very simple, just ask in your mind what's your emotions right now and the first word or words that come up that's the feelings you have.
2. "don't buy into it" - and literarry means to tell yourself however way you want to, not to buy into whatever stupid shit that come up in your mind (ex. i'm useless, no girl is interested in me etc)
3. accept it - accept the emotion as it is without buynig into that stupid shit that comes along with it
4. let it run through you (pretty self explanatory )

Now don't think of this as a magic pill that will make all your problems go away. It will just make you feel better for the moment giving you some balance to deal with your other shit.
And for the love of god, don't quit your ambitions just because of some nasty bitch, just go to another volley club and everything is settled.
And to get rid of the "hurt" feeling, let time do its thang and after that you can go talk to girls again (it's not a really good ideea to push through the pain because it will only get in your way).
