So sorry for your pain and this situation you're facing. You may feel alone there in the city, but you will not be alone here. There are many people here on the board that are in almost the same stitch as you, and everyone can certainly be supportive.
Have you read DR yet? I'm sure the coach told you about it.
Detaching and not pursuing him is what you need to continue doing. Wait for him to contact you, then be friendly but not clingy or desperate acting. Don't discuss the R. If he talks.....just listen. Agree when you can....validate when you can.
When you're home and feeling lonely....come here and talk to us. Reach out to others on their threads. It will help to build your support group.
Take care of yourself. That's important!
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
