it's funny. Not for you, but my friend is going through a breakup. Well, actually, he's over it and she's getting there. The best advice i can give you is to relax. Do you have any really good friends? Try distracting yourself, and even taking your anger out in video games. I wish i could help better, but since i don't know you personally, i'm not sure what else to say. I'm sorry. I'd love to be able to help more.
And to answer your other question, people just jump into relationships now. They don't get to know people for who they are; they base everything off of who they think they are. I don't know if this is the case for you, and i sure don't want to accuse you of it, but from my experience that's what happens a lot. Like, i love my girlfriend to death, but there are times where i find out new things about her that i didn't know. The best thing to do for that situation is to spend the extra time getting to know someone you think you like. It can make or break your relationship.
If you want, I've found recently that i'm the one who gets asked about relationship problems, so if you wanna talk about it, you can talk to me (if you want, i'm not one for forcing people to talk).
Well you have two options, be friends with them or ignore them, but first do what the above mentioned. Go be with friends,it helped me whenever something went wrong i just spent the weekend over at a friends house and I ended up getting over things pretty quick, especially this last time. If your friends really are friends they will help you out and get your mind off of everything.

I understand a bit of what LoG is going through. I have the same issue. I have found that my ability to let go for good is a multi-stage process. I get angry, then sad, then I feel like it's somehow my fault, then I pity myself, then I get apathetic, finally I let go. The key for me is to work through those stages in a healthy, constructive way. My dogs help keep me company as well as provide a listening ear. My friends also may provide an ear or other support, but mainly I have to get through the ordeal on my own. I keep busy...work, hobbies, gaming...anything that serves as a distraction. Time really is the only surefire cure....it's just the waiting that sucks.
I have felt this way as well. Just spend time with your close friends and get your mind off of things. Thats what I do when I feel down so hopefully it will work for you as well. Lots of people need time to get over their Ex's, especially when they were the one dumped. All we can do is pick ourselves up and keep on going.
