How to move on?.......

Dorraine
After being together for 3 1/2 years he left. Not really sure the explaination he gave was not valid enough to me personally. So I was wondering how do you get over someone who you planned a future with. I have him everything and what's worst is that my daughters fell in love with him also and wanted us to be a family. I feel like I failed them big time and not sure how to even get over it. So much hurt and confusion and pain. Ugh help.
