I didn't read your first post, so I don't know how old you or the Scorpio is, but I can tell you a few things about Scorpios as I've been married to one for almost 4 years. They can be sweet, charming, attentive, adoring, caring, and make you feel like you're the most incredible woman they've ever met. Ah, but once they "have" you (i.e., married or in a committed relationship), they can become distant/aloof, secretive, manipulative, controlling, and you end up wondering what happened to the sweet, vulnerable man you fell in love with. It's not just my experience. I have a friend who was also married to a Scorpio, her father was a Scorpio, and she's done astrological charts for decades. Scorpios love women/girls (and are very sexual), they love the chase, but once you're theirs, they seem to put up a wall and shut you out. It can be a lonely existence unless you're strong and have your own friends, activities and life.
Beware: resist if you can because it will probably mean heartache if you fall in love with him. Keep him as a good friend; they're great at that.
