Long term lurker here,

​

I'll try to keep it somewhat short but for context: I was raised by a very selfish single mother who doesn't know how to be alone thus constantly put me in abusive households throughout my childhood. I recently turned 20 and i'm making enough to be financially independent so I'm moving in with my girlfriend (Not here for advice on this, I know the trp opinion but i'm playing with the cards I got right now) and decided to tell my mom a month early. She made this a whole shit show as she's now old (late 50's but lifetime drinker and smoker) and has pushed anyone in our family away from her (and me) so i'm basically all she's got left. She screamed her life away and told me I could never come back once I left, I simply replied "wasn't planning on it" and shrugged as she kept nagging. She proceeded to go on a 2-3 hour drinking binge where she disrespected me and my girlfriend. My issue is that my lease doesn't start until mid September, so i have about a month and a half of this bullshit to deal with. Considering my mental well being and comfort and also considering finances, is it worth pursuing leaving right away and just staying at some type of extended stay hotel or airbnb until my lease begins or should I just stick this month out?
