Men and women can be friends, its whether or not both parties are willing to accept that......is the real question. As for him reaching out after 15 years there maybe something there, I would not read into it anymore though. He may just want to be friends......
As mckenzie asked.....are you involved with someone right now? If so why ponder the thought of pursuing him? He is with someone, take this as a start of a friendship and go at it day by day. See where that takes you and don't expect anything more
