Exclamation Connecting ungrounded light switch to outlet

I have an old light switch which does not have a ground wire...very old Romex
I am trying to connect an outlet (two wire) to this switch wiring.
when I do so, the light when on turns off the outlet! When light is switched off outlet has power!
what am I doing wrong?

Ground is not relevant to function but a neutral is. If the switch has only two wires and there are no others you don't have a neutral, just a hot in and a hot out.. You need a neutral for the receptacle to work.

Even if you had a neutral if it is a new receptacle you couldn't use the switch wiring because you can not extend an ungrounded circuit due to the fact all new wiring must meet current codes.

Ok. I was afraid of that. House is 60+ years old. I can't get in attic to update wiring as it is a 4x4 space and full of hvac stuff. Opens beams on ceiling too.
Tell me, is it unsafe to leave as is, with outlet hot when light is off, and outlet dead when light is on?
Until I can afford to hire someone to retire main wiring, I am wondering if I should undue outlet totally.
Appreciate your help!

Yes.....it is unsafe to leave it like that. That is a totally useless receptacle and should be disconnected.
