Most Helpful Guy
It sounds like he cares about you deeply and probably loves you very much if you have met his family and he has met yours. Sometimes people are afriad to say it and so they just do not say it and it sounds like you guys might both be a little afraid to say it because he does not want to ruin what you guys have either

Maybe you should just go ahead and say it, just so that the door is open for him to say it! It's possible that he's also nervous to say it, in fear that you don't feel the same way. And, when you tell him, you could make sure he knows that you don't expect him to say it back, but that you just wanted him to know how you feel! If you've already met a lot of his extended family, it would seem to me that he, at the very, very least, cares about you very deeply and plans to keep the relationship going for a while.
