Dear Barbara:

As I read your post, it seemed to me that you are lost in the dark in regard to dating.

What I would do if I was you would be to send the friend request of B. Then wait for a response.
This is what you do when you are in the dark, you take one little step and you wait before the next step.

If you take my advice and send him a friend request (step one), then wait for his response. If his response is to accept your request, please post again and I will be glad to help you with step two.
