Manifested SP but he’s showing up in my reality in a weird way

So I manifested my SP months ago. We went from no contact to him basically living with me. So we are always around each other. However, he still acts in ways that show he doesn’t love me. We are basically friends. And we r both dating other ppl. I want him to fall in love with me again, and want a relationship with me again. How do I do this? What did I do wrong?
