B, I am so sorry you are not feeling good today. Embrace those feelings and then let them go. You are going to have ups and downs for a while because you love this man and it was so sudden as to what he's done and said to you.
He got off the train long before he announced to you that he was not in love w/you That's why he doesn't "feel" anything right now. Unfortunately, he's quite a bit ahead of you in shutting down his feelings. You, on the other hand, are just getting started. I'm sorry.
Can you do something nice for yourself today? Maybe purchase some flowers or do a bubble bath? I wish that I could offer you more in the way of support.
Take care of yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
