Well, I wouldn't worry about dating yet because no matter what happens with you and XH, you are NOT ready to date so I would put that thought out of your head.
The best advice I can give (and it's how I cope) is not to think of the future and just take each day as it happens, try to enjoy the good times like concerts etc and not analyse stuff too much.
When I look too far ahead I always end up picking a fight with my XH and making myself miserable. We get on better when I go with the flow.
I can't tell you how long to 'try' for, but only what helps me deal with my sitch.
