Hi John,
The pressures of careers and daily living can cause huge stress on a person and this can affect your relationship the way it has yours.
Women are such wonderful, complicated, lovable human beings arent they. When they are gone it can drive a man completely nuts.... You were confusing her and she felt your pressures were also smothering her...
I do not wish to go on about too much detail on how to get your girlfriend back but suggest you find real honest advice on my blog
