How would my status be if i moved in with my boyfriend jan 2022. and i make the most money. would we file jointly or i file head of household and add him on?

If you weren't married by 12/31/22 you are still Single or Head of Household if you have a child.  You can't claim your boyfriend as a dependent unless he made less than $4,400 total for the year.  So you each file as Single.  No change by living together until you get married.

Your BF cannot be a qualifying relative dependent, so you cannot use him to file as Head of Household.   If you have a qualifying child dependent you can file as HOH.     As VolvoGirl mentioned, unless BF made less than $4400 in 2022 he cannot be claimed as your dependent at all.  Both of you just file as Single.   You cannot file a joint return unless you are legally married.

Even if your BF qualified as your dependent (he lived with you all year and made less than $4400), he would still not be a qualifying person  for Head of Household, because he is not related.  You would still file Single.
