Toxic mom (NPD) being flirtatious around my boyfriend, I dont know what to do. What should I do?

She’s a single mother age 50

Acting flirtatious and doing all the sexy body language bullshit behind my back. When I got back from the bathroom I saw her being touchy with him.

she has always been salty towards me whenever me n boyfriend is around and when he’s being nice to me

not even once she mentioned that why would my boyfriend date someone like me

she makes upset face when she knew my boyfriend makes me happy or laugh. She never give good response when I told her good things.
