I'm slightly conflicted?

OK so here's the deal
Back in 2016 I started working with my brother in law at his job just your everyday regular run of the mill fast food chain and I meet a guy fellow coworker... after about half a year there I was having some housing issues roommates didn't want to renew the lease cuz of the landlord not wanting to fix anything, he's 2 years younger than me and lived with his parents going to school , saving more the normal stuff we become friends he offers me their guest room I end up living with them, following year 2017 around March or April we end up dating... fast forward to 2021 on Christmas eve he proposes... now here were are in 2022 and that's where things become a little bit weird I started a new job he starts working another job still live together everything should be fine but now we're constantly fighting over the stupidest shit ever putting away the laundry, making the bed, just small things that could have been easily fixed so at this new job I start hanging out with some coworkers (guys) he's chill doesn't mind total trust and vice versa but lately I've been feeling unstable mentally emotionally the usual now normally I can handle it with easy I know the tricks and tips to keep me from snapping at anyone... I've started hanging out with my coworkers more often than my fiance... I only hung out with a certain coworker once but we get along just swell and he's very funny, charming, good looking? I'd say so but not enough to stir my heart... that is until recently... i hung out with him once and of course drank... my dumb ass got blacked out luckily enough he's a good guy I was not taken advantage of... but lately every since then I've been really happy too see him like just a little wave makes me happy and at first I didn't want to admit or maybe I just haven't noticed until today but I'm so confused am I getting a crush on this guy or am I just self sabotaging my relationship because things haven't been going well?
