Fatma, well, so sorry you're in so much pain right now. It does hurt, no doubt. But you can't control another person's free will or actions, so really, the only thing you can do now is to take care of you.
The first thing you have to do is NOT take it personally, although that's really the hardest thing to do after a break up, because it feels like the most personal thing in the whole world. You need to start taking care of you. Get involved with family and friends, what's going on in their lives, and what you can to do be there for them, start up a new hobby, read that book or go see that movie you've always wanted to but never had the time to. Paint your toe nails a crazy new color, take a nice long walk in the sunshine. Use this time to learn whatever lessons there are to learn from this experience and to grow from it. It will take more than just time. Time itself does not heal anything, no matter what people say. You must actively work at getting past this and feeling good about yourself again. Good luck to you.
