It seems as though you're moving in the right direction, if it's been about 2 months, its safe to have that convo any time now. Just do it when the time feels right, and preferably in person. Perhaps over dinner? Why don't you ask him out, and make it a special thing? Make it a romantic occasion, and "ask him out" officially! That day could be your anniversary date if you guys continue to go out! Yeah. That's what you should do. I have good ideas. Lol. You're welcome.
May the wind always be at your back and the sun upon your face. And may the winds of destiny carry you aloft to dance with the stars
