Dear Blondie10 ,
After reading your post a few times, I just had to respond. What you describe sounds like what I also went through with a Scorpio male . My Scorpio friend & lover was in and out of my life so many times it would drive anyone crazy. I heard the same thing "I need space!" I wished him the best in life and gave him his space. When you mentioned he is outside your house to prove a point, that too happened to me. I too would find him outside my house. I would be out on dates with other guys and there he was, in his car. It happened so many times that next , he was inside my house talking with my parents just hanging out. This went on and on for a few years. Well, one day I said too him, "I have given to you seven years of my life! I want a commitment from you. A promise ring would seal our relationship!" If not, than it's over...good bye! Well, surprise for me that x-mas in front of His parents and His friends, I opened the box to find a small but beautiful diamond ring. Been married 25 years with two sons to this Scorpio man.
