How can you tell if someone is interested in dating, or just something casual, when you have known them for years?

Peter and I went out early last week.  Was it a date?  Are we just friends who will stay friends?  There is definitely chemistry between us, there always has been.  We’ve known each other for 7  years (though we haven’t seen each other for 5 years), but this time it seemed like he was actually interested.  Maybe it’s my increased confidence, but I felt like he was trying to impress me and he WAS indicating through body language that he was interested.  But….who can tell?

I am kind of making it my mission not to be the pursuer these days.  I have spent too much of my past doing that and I think I deserve to be pursued the old fashioned way: an interested guy asks ME if he wants to take me out.  Even after one date I don’t want to be the one asking for a second.  But my question is…are all men capable of this?  Is it too much to ask to want to be modern in most ways, but old fashioned in this way?

All I know is, I think I would like it if Peter asked me on a date, but I won’t be asking him to go out unless it is as friends…
