28m can’t take 25f anymore

I 28m and my girlfriend 25f have been together for just over 3 years and it’s really starting to feel over. For background she prefaced the relationship by telling me she is crazy and needy and that if we were gonna be together that she’d be moving in (to my parents basement) immediately which I was just kind of like yeah sure fuck it with cuz I don’t have much else going on. All my friends moved away long ago and I don’t do much besides go to work, do chores for my parents, hike and fish, which she seemed to like. We did get along really well in the beginning even though we spent basically every waking moment together as we both worked for the same department of the same company. She would have outbursts and it’d be tough to deal with but it felt manageable and she’d always come back around to being sweet and bubbly once we went for a hike and caught some fish and whatnot. Overall I felt great about it but that only lasted a few months.

Since then it just feels like she straight up despises me and is insane enough to berate me about it forever instead of finding someone or something that actually makes her happy. She literally ALWAYS has to be negative about something. I remember thinking the first year we were together “whew we got through the holidays. That was stressful but things should settle down now.” And that period 2 years ago was the last time I had hope for a life not constantly plagued by whatever bullshit she’s upset about now. She is immature, jealous and paranoid to the point of throwing fits in public over the littlest things. For instance because I said “thank you very much” to the girl giving me the order in the McDonald’s drive thru or my personal favorite her tearing thru wal mart just throwing shit on the floor for me to pick up because I accidentally looked in the direction of an attractive woman for a literal split second.

Anyway fast forward to today and nothing has really changed. She’s just as much of a constantly negative sky is falling nightmare of a person to deal with despite the hundreds of times she told me she’d change. Despite never even coming close to paying rent to my parents which I covered for the both of us either monetarily or through literal back breaking labor like bucking and splitting 6 cords of oak in april and may, she now wants me to basically do a full restoration job on her grandparents house so we can move in there and I can start paying rent to her dad. Which honestly I wouldn’t mind doing but not for or with a person who makes me feel like such shit all the time.

Oh and she also got a new job at a daycare about 2 months ago on some purely grass is greener bullshit even though I begged her to just stick with the job she had. So now on top of everything else she’s a fucking walk biohazard and has been getting me sick every other week with some of the gnarliest shit I could imagine. I currently feel like garbage with one of the worst flus I’ve had in my adult life and she just treats me like I’m a lazy piece of shit.

So I guess the question is on a scale from 10 to 10 how fucking retarded am I?

Also sorry for grammar/run on sentences I am pretty out of it atm.
