This is sad wonderful and great I too can relate and I know the feeling sucks and u feel it gone forever,,,I still have not found the one but I must believe he is out their waiting,,,you will find it one day
Mine was 10 months and we were also engaged,,,he left me and zero reason,,to this day I remember and think but we all must learn to let go which you don't want some guy who doesn't deserve u,,, u will one day find the one who fits ur broken edges of ur heart
