You are a nice, friendly girl who gives the guys a bit of a thrill at squash. Nothing wrong about that. You still have unfinished business, but if that gets resolved and you are still alone, no harm in making a friend or two along the way.
I say whatever gives your confidence a boost is OK. And I hear you about a nice guy talking to you like a human. I have had that a time or two (thank you Lowes!!) and it is wonderful. Thanks to all those guys out there that, interested or not, make you smile!!
