"This is all part of what I'm saying. This is another place in my life that I feel very settled and comfortable. I'm in a relationship right now and it's comfortable," he said, later adding that he's been able to sit down to start "really thinking about all that stuff, that's made the relationship that I'm in now even more meaningful and opened up the possibility of things like being married, having kids, defining a new version of happiness, life, wellness." "It sounds hokey and whatever, but it's real and for one of a better word, it's what I'm working for. What else is there other than that?" he added before confirming that he is "very much so" in love.
