How to approach my wife

I’ve posted a little time ago my wife has BP1 and out of the blue discarded me , I packed things and left but she is still at the apartment she jumped immediately into an affair with her coworker is saying it’s the happiest she’s ever been barely communicating with me and goes cold we share a car I haven’t seen her yet but I need to start working in our apartment, not sure how to approach my goal ultimately is to be here for her and help her through this but with it being so fresh she is absolutely giving me the cold shoulder and found out today her grandma who lives with us stated she has not been taking her new meds that will start bringing her out of this mania .

It’s a mess I just want my wife back and she’s absolutely “in love” with some random coworker and that coworker also had a relationship but now I feel like they are putting each other very hard only have heard updates from friends

This is her first mania she’s ever done this and I really don’t know how to navigate it her antidepressants are responsible for this mania and it’s not a normal one where she’s rapidly changing it’s a very dopamine filled one and she is seeing butterflies and rainbows and idk how to approach her she asked for space I’ve been doing my best it’s been week exactly I know it will take time but how can I support her back to baseline and get my wife back this is not her
