Aquarius desperate to get her pisces back!?

ok so I am an aquarius born Jan 29th, and my ex is a pisces born March 14th. we were together for almost 7 years. we struggled alot during our relationship, not because we weren't in love, but financially and life issues in general, we were young and starting a family with virtually nothing. we have both done some things to each other that in some cases people might say are unforgivable. I love my ex with all my heart, but as an aquarius..I didn't show my emotions or romantic side as well as him my romantic pisces. He has since moved on and found a scorpio woman. I have always heard that those two signs are made for each other. He tells me that he doesn't love her and that he will never be with her for several reasons like she has 2 kids by 2 different guys. (my ex and I have 3 children together, the only children for the both of us) He tells me that he loves me but I have hurt him and broke his heart because he really loved me and I was his queen. We have split up and rarely talk now, we were always the Bonnie and Clyde type. he tells me that time heals all wounds and because I am the mother of his children that we will always have a chance. I am so scared to lose the man I love to this scorpio woman. do you think that he will forgive me for my mistakes, as I have forgiven him for his? Do you think that I have lost him to his scorpio fling?
