Oh girl... I so know the feeling. The guy I was with for almost 10 years, engaged to and owned a stupid house with broke up with me, left me to cancel the wedding, sell the house... all while still trying to co-exist. Can you kick him out? I mean he is the one who broke up with you? I kicked my ex to his mothers house until our house sold. He also was very callous and mean about it, he once told me a long time ago that the guy feels like they have to be mean about it so they leave no room for false hope with the girl. I guess it makes sense, and there is no happy medium right? You break her heart and the only thing that is worse than that is giving her false hope afterwards by trying to offer comfort or support. To tell ya the truth girl, if he was to offer you comfort it wouldn't help you, cuz he is the cause of your pain.
Im so sorry you are having to go through this, PM me if you want to talk.... I can also direct you to another forum (where Im an admin) for dealing with break ups, where you can chat, vent, cry, scream and make some friends while you go through this.
It took me over 2.5 years to get over him but I am now and looking back, my break up was a LONG time overdue as well, so it will get better! I promise!
