LMA:

Ok, we can talk about that.

All human relationships were created by Hashem for us to either learn something about Hashem, or to be able to emulate Hashem.

Thus:

We have fathers so that we can understand that Hashem treats us as a father.

We have children so that we can emulate Hashem by doing for someone with no expectation of a return. (and yes, Hashem made the world and could have made us have fathers and not children. Don’t ask me how.)

We have spouses so that we can understand that our relationship with Hashem is like a spouse.

We have kings so that we can understand how Hashem relates to us as a king.

This is clear from shir hashirim, which uses the romantic relationship to analogize to our relationship with Hashem. We are supposed to do that.

You ask whether a single person can have a relationship with Hashem. Yes. But perhaps not the same way a married person can. And perhaps an orphan cannot understand the way Hashem acts as a father.
