Hi Frankguy,
I think that is a good idea, to wait and then try again. I know if it were me in your situation, I would want things resolved as quickly as possible, but that is not always possible, especially if she is not answering her phone.

It seems you think this friendship is really worth saving, so I hope everything works out for you. If you ever want to talk, I am here for you! (And no, I wouldn't think you are too needy!)

Love and Best Wishes,
Zen
