I care about him but I feel like we are making no progress in our relationship. What should I do?

So we are together 7 months 31 and 32 yo. He is very closed, reserved and emotionally detached and I felt like with time it will ease up but it's not. We are dating like teenagers, meeting up for a sleep over every three days and I feel like there is no progress made in terms of attachment and needs.

I was in 5 years relationship before him and we lived together so this set up is not enough for me. On the other hand he was alone for 7 years, casually dating and he never lived with anyone. So he doesn't really mind this rhythm.

I don't really know how to approach it as I am getting kinda bored while lacking everything. This way of dating I outgrew and it's making me feel more alone than in a relationship. Any thoughts or advices?

NOTE: I am mostly bothered by his casual approach towards not meeting up regularly, as if he isn't bothered and having zero needs, while at the same time he insisted on us being serious, meeting families etc.
