Vapo said it in a very succinct manner. That's what I w as trying to say (he used medical references too, and I'm the nurse)
I hope I didn't come off as insensitive, and if I did, I am sorry. I can sympathize as in my last relationship ended when we had a great R. Circumstances in which we know the pain would be much greater in the future.
You are not mourning not only one lost love but two. That is extremely difficult. But I know when you get through this there is a lot of gifts on the other side.
And if you are meant to be with either of them down the line, you will be. I truly believe in that.
You come from a good place. Now is the time to get to know more about yourself as someone not in a relationship. get to know you. Fall in love with yourself without having another half and you will be ready one day to add to your life.
