2. He understood he wasn't the best for you, and despite being sad he knew you'd be more happy with someone else. Either out of respect or love he sent you off, knowing it was best for you.
3. He simply wanted to end it too, and was happy you did it first so he didn't have to feel bad about breaking up.
