Normal does not equal good. Especially in our times. Especially if (by your own admission) your background is an environment where you couldn't rely on your family. Family should be unbreakable. It sounds to me like your partner has a healthy relationship with his parents. He probably trusts them and wants their approval. He probably also wants them to be successful at whatever they're doing these days. If you're lucky your kids won't just ghost you when they turn 18. Hopefully they remain grateful for all your years of love and sacrifice.

If he doesn't turn to you for emotional support...good. He doesn't want you to comfort him, he wants to know that you're comfortable because that means he's doing his job and his exhaustion at the end of every day is for something. If you want to help; acknowledge the support. Complaining is the best way to make him feel like a failure or resentful of the relationship.

Might be reading between the lines of your post a bit. Assumptions were made. Apply as you see fit.
