Bro. X, you will be fine. Whatever happened these days will be your sweet memory tomorrow. Afterall, one may not spend the rest of his life with the one he loves most.
Before I have my favourite as T c-9, I broke up with my ex-GF. We have been together for a couple years. Very very sweet memory. But at the end, I think my favourite is really the one who is best situable for me. Breaking up with my ex-GF is painful.

She told me she love me and want me to be happy and therefore she respect my decision. But she will spend 3 years to wait for me to come back to her. I feel so much pain, still hurting right now. Hopefully, maybe many years later, I can still met this lovely girl and find out that she lives happily without me.
This is the decision that I make. How about you?
