I have ended two marriages and some shorter relationships that weren't really serious. I think it was all training for my 3rd marriage to my "soul mate". That isn't perfection, but we're working on staying together and being happy with each other.

I still remember the first few things I did as a single person...going to a party alone, a costume party, no less! And I felt good being there by myself, which really surprised me. I was so anxious in the car driving to the party. Afterwards, I felt such a sense of accomplishment. Hope things go OK for you too!
