Hi Mark, It sounds lovely to me...and sounds like you are both enjoying this flirtation and may have feelings for each other. If you are up for it, I might suggest that you let her know you would love to ask her out and want to make sure she is comfortable with that and if she isn't that you are still okay and would love to continue to enjoy this fun friendship. This way you open the door to a yes from her but alos let her know you are fine either way if you have misread things.
let me know if I can support you further. If all good for now, please click on the rating tab to rate my support so that I may be credited for my time. Thanks for your understanding with that. I am here if you need.
