How can you tell a SCORPIO man wants a relationship?

He said he had been intersted in me for several months before we recently started seeing each other. He was interested in me long before I even realized it. He told me of his past rough relationships and that I was the first girl he has taken out in 2 years. He told his family of me. He has introduced to his closest friends. He keeps in contact w/ me constantly. He does things for me. He is very big on PDA and letting people know we are seeing each other. He does not pressure me about . He is caring. I know all of this sounds solid but I ask because it seems to be moving so fast. Do scorpio men usually move fast?
