Not all stories are the same.
Wildcat,
Usually I agree with you approach on keeping distanct and not contacting, but in this case I just see it as a little different. First they dated for two years,, problably not the case of "she was feeling smootherd after two months". Second One_Life mentioned that she is not one that enjoys feeling ignored. I do not know all the details of the story, nor will I assume that I do. But after a two year relationship and no contact for two months, I would believe that two adults should be able to sit down and determine what is going on. There is so little information to always assume that you never contact them,, sorry I just don't agree. I think there is a point in time in which communication is OK. I am not saying pour your heart out beg the girl to return,, not at all, but what I am staying is after two months if you have a concern, then begin a conversation on small talk and ask some question on what may be bothering you.
The only person that could really know the answer is One_Life, for it is only he that knows the whole situation and who this girl is and her attitude. We as guys are all different, and all girls are different. Sure there are some similarities in which so many relationships books and websites strive for tatics and advice. Even when I read those books or view the websites, I do not believe they are rules written in stone, rather a guide to assist in the relationship game. They are based on the statistical average woman and man and the relationships in which they are involved, but they are not a conclusive set of tools to apply to every situation without fault.
