I get it. Your email was all about how we didn’t work before. But, what it really means is how we will never work. Simply, you never could love me. Sure, maybe you were still in love with someone else. Maybe you can never love someone that loves you. Maybe you just don’t value yourself enough to allow that.
What ever reason you use to convince yourself, the simple facts that you don’t love me, didn’t love me, and don’t want to try again. So, what reply did you expect. You said it all. There really is nothing left to say, because there is nothing I can change.
