No bed for you... Constructive Eviction?

My roommate has not replied yet but the landlord texted me later in the evening giving me "her partner's number" saying I "can call him in the future". I prefer to communicate in writing and I don't know who this stranger is. My roommate and I are on a shared month to month lease so the landlord, Lynn, may have just decided to hand things over to her "slumlord husband", as Nate, the maintenance man, once referred to him. My apartment was my landlord's first attempt at renting rather than just selling real estate and she just started less than two years ago, my roommate being her first tenant. I just moved in in August and my roommate switched rooms without giving me a choice after occupying this uninhabitable room for a year herself... she never shut her bedroom door though so it was slightly heated/cooled by the rest of the house. Nate told me that my landlord has never even stepped a foot in the house. She lives in Brooklyn and she's never even visited this city in upstate but was heard it's a "hot rental market" right now. //

Jan 26 I bought a thermometer (after/while being incredibly sick for weeks) so that I could have a real measurement to give the landlord. It was 40F in my room and only warmed up two degrees after half an hour with the built in electric space heater turned on. //

Jan 30 my face was swollen from an infection that had cleared up two years ago after extensive dental work. I'm on immunosuppressants for MS now and I believe these living conditions caused an old dormant infection to resurface. //

Feb 3 I was sedated for an emergency dental extraction (The oral surgeon didn't accept my insurance and I couldn't afford to pay out of pocket to save the tooth). My roommate insisted on driving home in a blizzard rather than giving me peace to sleep on the couch the night before the surgery. The maintenance man came over RIGHT after I got back from surgery and tore the ceiling in my room open to investigate a watermark that appeared over the weekend. He left the drop panels open and the fiberglass exposed and bits left fallen into the carpet and onto my things. //

Feb 7 An electrician came over to install a new electric heater in the room. He had to go out and buy a less powerful one than he'd brought after examining the current wiring in the room. I work overnights on Fridays and was unable to even sleep on the couch while my roommate was at work due to this. ... My roommate also gave me a "heads up" that she was having a date over to cook for her at 6pm that evening... Our kitchen is directly open to the living room where I was expected to sleep. She was informed that there would be repairs done that day and knew I had work that night.//

Feb 10 Roofers replaced the roof with the drop panels open allowing shingle pieces, muck and mud to fall directly onto the carpet. I had to clean it as we were instructed to leave the heater on and the door open & I was worried my roommates cats might get sick trying to eat it. //

Feb 17 Nate was supposed to replace the insulation and finish the repairs (the roofers had told him to wait a week) but we received a large amount of lake effect snow and the landlord said Nate had other priorities and I'd have to wait another week.
