To all those who have said "dump him"....bit late and it is rather unhelpful as he has dumped HER.
Now, if he is the "go-ahead type" then he makes a good point ( behind every successful man there is a strong woman)and perhaps Linkedup is not that woman. There is no easy way to say to a woman "you are not the woman i wanted, you are the woman I've got" and it takes rather a special kind of man to face up to reality ( it takes women longer and more dramatic).
Contact him if you feel that would help, as it would do no harm but prepare yourself for the period of chest beating, crying, depression and worthlessness which everyone goes through in you circumstances. You could meet the love of your life, handsome, personable, understanding who would make you forget HIM......someone like me.....;-) but i doubt it.
Good luck.
