How do I deal with a break up?

Ugh . Just went through this myself . Yes, you could try to get back with her . But remember, it ended for a reason . Just because you try doesn't mean that she will take you back . My suggestion: move on, although it's a hell of a lot more complicated than it sounds . Pick up a new hobby and hang with some friends that know how ya feel . I myself got started with paint ball because of this a while back and I'm loving it . But either way, you gotta have some support (yeah cheesy I know) until you come to terms with the break-up .

Whatever you do don't delt yourself .
there are two options you can choose . Try get her back . By finding out why she dumped you, and depending on the reason you could get her back . Or the other reason is just try to get over it .
i know its hard to get over something like that . Trust me . But you always become better off .
just try move on . Find someone new, or even just hang out with your mates
