Double Life

I have been with my Fiance for 18 years since we were teenagers. We have a home together and have been through a lot together. He has grown to be my best friend and I do love him dearly, but 5 years ago I fell in love with another man (C) and have been living a double life. The other man knew I was engaged and has waited for me to leave. The love I feel for (C) is unlike anything I've ever felt. It is like he completes me. But a few months ago he ended our relationship saying that he feels that I will never leave and that I love my Fiance more than him. Understandably he is quite bitter and has felt second best for the past 5 years. I am devastated without him and can't pull myself out of this constant depression. I have only ever been with these two men in my 33 years of life and never thought I'd ever love another man other than my Fiance. But this other man (C) actually made me see that there are different kinds of love and he is my soul mate (best way I can explain my feelings). What should I do?

If C is taking you back, if you leave your fiance, you have a choice. But there is of course a risk that you will miss your fiance, if you live only with C. C might also leave you anyway. You do not know what will happen if you two live together. It might not work at all.
