Can someone contact me soon please!

My landlord rented to me in December of last year. (I moved here from Texas almost 14 months ago.) He promised a safe, clean, quiet room in his rooming house for me and my girlfriend. (Where he lives also).
From December 30-May 28 there was another tenant here that we (and other tenants complained about): very loud, smoked marijuana indoors, had multiple loud guests over and stole food. (The neighborhood complained as well several times). He promised for 4 months that he would have her leave, but wouldn't enforce it. My girlfriend said she was leaving because the girl threatened to burn the house down and/ or report it as an illegal rooming house. (Which turns out to be the case).
Things did not change at all because he kept procrastinating (would not file eviction on the loud tenant) and as spoken my girlfriend left. In turn I lost my job because we were a subcontracted team; so if there's not two of us it means no work. I told the landlord this and initially he admitted it was his fault. Now he's slipping notes under the door telling me I need to leave in 3 days or less because I can't pay him! That's not legal! I need help.
