how do I move from friendship

[whitneypinch]

Ok, so here I am 18 months after the bomb. We have been divorced now for 5 months. We are friends and we have been going out about once a week for a month (lunch, errands, bike rides). We are starting tennis lessons in a day (once a week).
My ex W says she likes to do stuff with me (I initiate mostly) but that we are just friends.
So....how do I move from here? Let's hear from you WAWs.

Thanks
