I've been chatting with a girl at work for a while now. I'm pretty sure she likes me and is waiting for me to make the next move and ask her out on a date. I want to make is soon before she thinks that I don't like her. But it seems like every time I talk to her I keep thinking about her age. She is going to be 21 later this year and myself 27. I just keep thinking that she is a year younger than my sister.
I haven't been on a date in quite a few years now. Maybe, I'm just using her age as an excuse to keep her at a distance. Is this an acceptable age gap?
