Has anyone's boyfriend changed for the better since dating?

I have noticed how much my boyfriend has changed for the better since knowing him. He was always sweet of course, but he's so much more sensitive now, like he doesn't swear as much around me, more calm and less snappy and angry. I told him how much he's changed and he's noticed it too. He said it's because he loves me and feels more close to me. Has anyone else went through this?
