One of my big fears about putting things on ice for 12 months is that he and I will lose what we have .. at the moment, we talk almost every day, usually for a couple of hours and we have just gotten to the point of finally figuring out what we want from each other so .. it is frustrating to think of giving that up.
You don't have to give up contact.
You don't even have to give up the romance.
You could give up expecting to have it RIGHT THIS MINUTE and just wait til a better time.
Could call it a "friendship with romance potential" for now if that helps you feel better and be free to date others in the meanwhile.
Can a relationship be picked up down the road?
I think you mean "Can a romance be picked up down the road?"
Sure. Why not? Anything is possible.
