Is AUTHOR wrong in the post ? POST : I've been out of work 7 yrs because of undiagnosed illness, parents've covered food and given me housing. Celiac diagnosed last year when it'd gotten so bad I threw up every time I ate, was bedridden. I eat even a breadcrumb now, I basically have 3 days food poisoning

Characters:
Me: Mom in car wreck last June, got brain damage, needed live-in caretaker. Dad asked if I could delay job-hunting to do it, cheaper to keep covering me than hiring full-time nurse. I agreed, wanted to help, they helped me for so long

(F)Fiance:Been together~13 years, has aspergers

(FBF)Fiance's Best Friend:Met him 8 years ago as I deteriorated, became unemployed. He has OCD, copes by smoking weed(it does help). He's been very supportive of F through it all, while accusing me of being a lazy dead beat &amp; source of F's stress. In last year (after treatment), said he sees me improving and doesn't feel that way about me as much anymore, but time will tell

Backstory: 
F and I struggled for years not being able to afford to live on our own, managed by renting from friends. Most recent one is a messy hoarder, verbally abusive. F and FBF have been renting from him since July, eager to save up enough for deposit on apartment

Mom finished most therapy in March, still can't drive. I now have time for a 25-30 hr/week schedule

I did legwork to find apartment. F&amp;FBF want it ASAP, I'll not have had a job long enough to submit 2 paystubs to be on lease. F&amp;I can't afford 1-bedroom, we have to get 2-bedroom together with FBF

FBF, F&amp;I discuss apartment desires. F doesn't care, wants roof over head, we can figure out what we want. I want no smoking weed in the main areas of apartment, as it's my furniture (couch, rugs, table, dining chairs). FBF disagrees, he wants his own place where he can live as himself, doesn't need my furniture, only needs his beanbags, tv, coffee table. Fine, can he get an air purifier? No, if it bothers me, I should get one. Ok, Fine

One parking spot per apartment, others have to walk from guest parking. FBF claims dibs since he's paying 40% of rent, F&amp;I are splitting 60% for master. Fine

I want veggie garden on patio to do cooking for apartment. Some disagreements, but resolved. I'm happy, FBF feels magnanimous

ISSUE:
Everyone always eats at coffee table, kitchen is tiny, I'd like to claim tiny breakfast nook as a GF place, do all food prep at my table. Can't risk getting sick if I'm responsible for rent and utilities too. He doesn't want to be restricted from using a table in his apartment. I tell him it shouldn't be an issue, since I'll be making a lot of meals, which will be GF

"Yeah, I don't want to just eat that, I want pizza and stuff." That's fine, just don't put it on the table. FBF disagrees

F says we can just put down a tablecloth that I remove to use the table. I say tablecloths are porous enough for flour to get through. I just don't want to risk getting sick. FBF asks if this is "really the hill I want to die on?" Yes.

AITA?
