Hi everyone,
First I'd like to thank everyone for their advice and input, it has been extremely helpful in this situation. You ladies made some very valid points, some of which I didn't take into account in the beginning of this problem.
I have decided to just do as much as I can to forget about this guy and take care of myself, and be around people that put me in a good mood. I already know that it will be difficult to put on a brave face and fight back tears, especially since I had a 7-8 year history with Joe, and I loved and cared for him deeply. But I have pretty much filled up my schedule for the rest of the year to keep me busy and out of the house.
I went out with my co-workers last night after a store meeting, and those guys always put me in a good mood when I see them. A couple of them know about the break-up and had some very encouraging and enlightening words for me.
So, we shall see how this difficult process will turn out. Once again, i thank every single one of you for your advice; I really appreciate the honesty.
