Hello fella,

Sorry for what you have been through, this is awful for you.

However, this is good old fashioned heartbreak. And it's called heartbreak for a reason and it REALLY hurts. However you WILL get over this and you will move on and chalk it up to experience. We all go through this, remember you are still quite young and have so much life to live.

By the sounds of it, she was well on the rebound and just wanted a relationship to get over her last break up. Sorry if that's not what you wanted to hear but it's probably true and she just transplanted her feelings from her last relationship to your one.

Leave and move on. You will never have to see her ever again and it will be better and wiser for it.
