What moves can a guy make on a girl he's interested in if he's not sure if the feelings are mutual or to start flirting?

I am attracted to you and am hopeful that I can get to know you better. How about we venture out together some and see where it goes…I know “this is happening” and think it would be fun…and I would like to share it with you…mark this date off on your calendar and will workout times etc.
