What Should I Do To Get Her Back?

There is nothing you can do right now. Becos of all the game playing you put her thru you pushed her away and she is afraid to trust you with her heart again. She is obviously very confused and does want to be single right now to take some time out to work out things in her head, she isnt doing anything wrong by wanting time away from guys to work out some issues. Even tho she is talking to her ex doesnt mean she wants to be with him, maybe she just needs some comfort, or maybe she realised she does have feelings for him still and needs time apart from you to work out what she feels for him, becos its not fair to you to stay with you if she has feelings for someone else. Just give her time and support and she may come back.

Usually when someone says they just want to be single right now, it means until the one i want comes around! If she truly still loved you like she says she does, she would want to be with you! Shes just being nice. Shes NOT stuck between 2 guys. It doesnt matter that she still talks to you, her ex is getting to spend all his time with her. That should tell you something right there! You cant get her back unless she wants to. Doesnt sound like thats what she wants to do. I think you really need to move with your life as she is doing!!!
