Hi shimmy, Im really sorry about what happened to you
Don't get me started on facebook,lol its pure evil. I found out more or less (well saw tell tale signs) that my ex was cheating.
I checked my ex for a few weeks after we split on facebook, but the pain got too much so I deleted my account, as I didnt want him to know i was hurting by just blocking him and his friends.
Maybe your ex is all talk with this new girl hes talking to? Maybe he thinks he can make all these plans, but probably nothing will come of it. Or maybe she'll get fed up anyway.
Men always, always think the grass is greener on the otherside, and it never is (my male friend has told me this,lol).
There is going to be someone out there that will treat you like a princess, and you'll one day look back at all of this as a learning curve
Me and my ex split over a year ago, we were together 5years, and I'm single, but its my choice, I like being on my own and being me for a while
Plus I can buy whatever I want now, haha. And Im at uni studying art, so something good came of all the crap I went through
It will get much better, I promise.
