I have been seeing this girl for about a month now. When I say "seeing" I mean we have hung out a few times and have gotten close (no sex yet though). She is giving me mixed signals a bit... she is shy by nature, but I sense she is on the fence with me. On Friday she came over for a fire and ended up staying the night. We slept together (actually slept with no sex) and got close... we talked for hours and hours and I told her as she was leaving that I wanted to take her out on an actual romantic date. I told her to tell me what would be a good time for that. She said "ok" and we message eachother every day and she seems interested.... at least a little, sometimes I get this "colder" sort of vibe from her. I think she is on the fence right now.
I guess I am asking...what should a guy do to progress this? Should I be more assertive and tell her I am taking her out to a specific place and then ask if that's a good time.... or should I just sit back and let her bring it up? I don't want to come across as too pushy or needy, and given the fact I actually get nervous around this girl (yes I realize I'm not 16, but it happens) I don't want to be awkward with it too. What do you suggest?
