It sounds like you are doing fine, taking it slow? I would make a little plan and ask him for supper or dessert or something, not particularly fancy. Since you don't know him too well yet, he could be playing all the women, your flopper friend, looking for whatever he can get; you are right you need to get to know him better, learn about his saber, cool blue or red hot :-) and just see if something more is possible. Slow enough will give the other women a chance to see what direction he's moving (currently, they're free to invite him to dinner too) and you get to see how he reacts (if he is playing with everyone to see what he can get) and just kind of get a general feel for him.
