Just Friends he Says????

[driftwood]

he decided that he was not yet ready to date
when he is ready to date I would be someone he would consider dating.
I am not ready mentally to date at this time its all good.
But ... there is no guarantee that we will ever date.
How long do I give for him to get his head into the game so to speak?

The only problem I see here is in how you're looking at it. Instead of waiting for him, or waiting for you, why not try to build a friendship in the meantime. That's probably what both of you needs right now anyway. I'm not saying it would necessarily be easy, but that's why I use the term build.

You want to have a friendship in which neither puts demands on the other, and you don't see each other too often, AND eventual romance is not the only reason you're friends.

That way both of you are free to become involved with someone else if one is ready earlier than the other. On the other hand, if you do eventually become intimate, what better foundation could you start out with than a close friendship.
