This happened to me 5 years ago. I wasted 7 years with a man who kept saying we would marry but then would always find a reason not to. Looking back now, I think he knew for the last 3 years of our relationship that he didn't ever want to be with me. My lovely goddaughter has just had it happen to her. Why do men do this?
I know there can't be a definitive answer, just interested to discuss it
