Is my Scorpio ex coming back?

It seems to me that your Scorpio ex is trying so hard to make you miserable by keeping you in a constant state of confusion about his feelings for you, by being nice to you then being mean, by telling you he wants to be with you and then going out of his way to make you jealous by letting you know that he just talked to his ex earlier, and by saying he wants to be with you and then then disappearing for long periods of time. What does he do to make you happy is what you should be asking yourself. You say he's very possessive and thinks you're cheating, Are you, or do you do things to make him think so? If you are not,and I doubt that you are from what you say then probably the opposite is true. People who are suspicious and accuse others of behavior that is unwarranted are often guilty of the behavior themselves and their own guilt forces them to see this behavior in others. And where is he always going off to. There are so many nice guys out there, why waste time on one who clearly, is to much agony. Find somebody to love, who wants to love you in return. He's out there, believe me.
