Ask her how her day was (women love that) Its seems like she likes to talk since you said you mostly listened. I would also follow up on something you guys talked about during that hour and a half. Something interesting must have come up that you can continue to talk about.
how bout, "How was your day today?"
I have the same question but Mine I s I met Her on church retreat and I like her but I dont have the to talk to her so I like her and she doesn't really know me but lots of girls think I am cute any way I think you should say hi then maybe ask a question and that might start a conversation or just talk about a subject that she might be interested in
