So I've sort developed this problem....
There have been so many times where I mistook conversation from a woman or friendliness as being interested or flirting that I've become incredibly risk averse. It is almost like I assume they're just being friendly because I feel like an idiot or an asshole for asking them out and making them uncomfortable when they were just being friendly. This effect is intensified with someone I know because I don't want to lose whatever sort of relationship we already have (burning bridges basically).
Just yesterday, I was at a bar playing pool and there was a group of girls sitting off to the side of the table. I noticed that one of them was a girl I worked with for a little while about a year ago so I walked up to her and was like "hey you worked at such and such right?" After talking to her for a few seconds her friend (who was sitting closest to me, the other girl was.a bar stool back) turned around on the stool and smiled at me. I kept talking to the other girl and to be honest, I can't remember now, but I'm pretty sure she did this again a few minutes later.
I was going to say "so who's your friend here?", or more boldly "so who's your pretty friend here? which I would think could potentially make both of them uncomfortable and make me look like an idiot. Anyway the reason I did not was I was thinking "dude, she is just smiling at you because you're talking to her friend, don't be an asshole and make something out of it it is not". So after I was done talking to her I just kept playing pool. Later on her friend was leaving and as she was walking past me she smiled at me again and I smiled or did some sort of acknowledgement. Anyway, obviously she left and nothing came of it.
Thinking back on it should I have said either of those things at the start? Would the first one have made it clear enough I was interested or would I have had to try to riskier flirty one? If I hadn't said either of those things should I have stopped her as she was walking past on the way and out and said something like "hey, I never caught your name. Blah blah. I'm going to lunch at such and such tomorrow, want to come?"? On one hand it is a calculated risk but on tbe other hand I feel like a doofus for asking a girl for her number and to lunch after JUST meeting her; it feels stupid.
More generally, how do I deal with my problem? Should I just take the risks anyway? I feel like if I took a shot every time I thought a woman *may* be interested I'd be one of those guys that comes off as desperate and honestly I'd feel like a doofus for asking so often. I guess part of that is because in middle and high school if you went around asking a bunch of different girls out word quickly spread that you were desperate and ridicule was sure to follow. Obviously college is a much bigger place but the same idea applies.
