Welcome to NGA!
I don't know a lot about lipstick plants but I'll try. I'm not sure what misting instead of watering will do for your plant. I suspect evenly moist but not soaked is what would make it happy. If you can't feel moisture an inch down, water.
Bright indirect light. No airconditioning blasting on it. It needs to be rootbound to bloom or its just not old enough.
My recommendations are: more light, more water, more patience.
Others will be here shortly to correct my thoughts.
