I know how that feels...was in a local pawn store a few years ago, checking out their guitar selections. Noticed a very attractive gal staring at me, she was talking to someone, but her eyes were practically enticing me.
I went on about my way, wanted to talk to her but I was still married and didn't want an entanglement like that for my daughter to dwell on about me. I wanted custody of her and wasn't about to do anything silly to ruin it. She stared at me grinning as I left, looked back from outside and was still being watched...sometimes wonder "what if", but I think I did the right thing by walking.
