shiduchim is a hard game. if he is good for you – go for it. no need to discuss with her. when you are already engaged – it will be her option if she is still a friend or not. if he is 100% right for you – do not wait. Look into it, date and figure it out. if nothing happened, she doesnt need to know.
IMHO, Not so tzanua to discuss dates and especially names with friends. Thats what mentors/ rebetzins are for. No names, just healthier. Wishing you much Bracha, and Mazal Tov bekarov!
