He said, "It's so hard for me to trust people. I've had a hard time believing that people are using me or are not really there for me and that writers are trying to get something from me and then use it against me.

"One of the great things for me is to trust me. I've made bad decisions personally and in relationships. These mistakes have affected my confidence in my judgment. It's difficult even to trust Hailey. We worked through stuff. And it's great, right?
