If you've been dumped girlfriend, I'm sure you're wondering what in the heck you should do now to get over the guy. You are more than likely feeling anger, resentment and hurt over the situation, especially if you were blindsided but hey, you know you have been through worse and you can survive this, too.
This is exactly the way you should be thinking. There's nothing wrong with hurting when someone you love is no longer in your life, and if you are strong enough to handle things then you will end up just being that much stronger when it's done. I'm not saying you should break down and sob in front of your friends, but your friends should also be able to support you while you're going through this. If they bail, maybe your first step should be to get some new friends.
Sometimes in life it's just as important to know what not to do as it is to know what to do. When you're trying to get over guy there are many things you just don't want to do, you will only keep the hurt feelings alive that much longer and you do not want to hurt others either.
For example, do not sleep with someone else right away. I know, you might think this will help your wounded pride and take away some of the hurt for a little while, but what about the other guy? Does he really deserve to be treated like a replacement for your ex? He has never done anything to deserve that kind of treatment.
No, it's best to just resist the urge to sleep with other guys at least for a little while until you can do it for the right reasons and not just to build up your own ego, ease your hurt, or get back at your ex. You will probably only make yourself feel worse by the way knowing that what you just did made you and the guy feel cheap and unfulfilled.
Another thing you need to avoid is the dumbest move of all of going out and getting drunk. It really accomplishes nothing and all you will succeed in doing is giving yourself a monster hangover. If you want to go out with your friends and have some fun to keep your mind off of things, then go for it. But if you want to drink yourself into a stupor either avoid doing that or at least stay home where you won't make a fool of yourself and where you will not hurt anyone.
Instead of engaging in these destructive behaviors when you have broken up with someone, try doing something positive that won't leave you feeling, or looking, like a fool. Join a gym and get in shape. Sweat out the anger and hurt. Why not take a single class or go back to school full-time? It doesn't matter what you do for yourself, as long as what ever it is that you choose to participate in is healthy and will eventually move you ahead in life. They can help you take your mind off your ex, and your anger and hurt, and concentrate on how to get over guy.
