First time Bi

Hey girls! I am a little confused about my situation and would love to hear your advice. 😊 I am hapily married but really interested in trying things out with a woman (my husband is very supportive about that)... I really like this one girl, but I have no idea what my next step should be... She has a boyfriend, but she is open to experiment with women (she told me she would love the experience of being with a girl, but tbh I dont know if she is still open for that now that she's in a relationship). Do you think I should tell her I want to experiment with her or just wait for the right moment and kiss her or something?  She is my friend, but not very close... We probably see eachother once per month, however I don't want to ruin our friendship because of that... What should I do??? 😁
