It really is a sad situation. I am sorry that you put yourself there. Try to continue with the family activities as much as possible. Do not pursue the R talks though. If he wants to bring it up, then let him then. There are a lot of open wounds on both of your parts, allow his to heal. Maybe, if you can continue the family activities with him and it is feeling good, then maybe he will soon be able to start dating you again. However, if you push it with R talk, you may just push him away if he can't heal.
I am no expert by any means, so hopefully others will chime in here to help too.
