Why does he keep telling me he is glad he doesn't have a wife or kids?

THE DETAILS
We've been in a relationship 3 years. We never talk about marriage. I never bring it up. I never mentioned wanting kids. I never push him for more, or to leave his job for a better one. I let him be who he is because I believe that you should accept people for who they are.

He mentions here and there that he expects more of himself and that he should be doing better, or could be doing better.

I simply reply, "you can do whatever you want to do, but it's up to you". The man is seriously talented and gifted.

However, he seems to be in his head a bit and thinks I want more. Our deal was to take it day by day. Last thing I want is pressure as well. I just want to be happy and he makes me happy. I can take care of myself financially.

I just wish he would stop bringing it up. It hurts to know that might not be my future. However, I think he and I might be together forever because everything is just so natural. I accept being with someone I love for 50 years and never getting married or having children because I believe God will be okay with it.

I just wish he wouldn't keep mentioning. Especially because it never crosses my mind until he brings it up.

I am not complaining, but I am trying to figure out what goes on his mind, and when I ask he just laughs and changes the subject. I don't push it because, what we both like is the feeling of safety and I don't want to ruin that with pushing him into a corner.
