I'm an Aquarius he is a Scorpio 12 years younger than me.

Well, I should say that you have 50 percent chance of making your relationship work and having a family. Aquarius and Scorpio belong to two different worlds. Although they are attracted to each other, they still can't find the "bond" that connects them together.

If you still want make a try, then you should be loyal to him because Scorpio will do everything to avenge if he finds that his partner is disloyal to him.
