I'm ruining our marriage......

Lately I've been in this bad mood cycle that I can't seem to break... I can't stand my husband's jokes or humor... We have not gone a day without arguing lately to the point where tonight he opted to sleep on the couch bc he can't stand me... It started since I got a promotion at work and they kept changing my schedule... Things just got out of hand at home so I asked to step down for the position... Since my prior position had been filled I ended up with a sloppy afternoon schedule which means I'm always home late. Lately I've been noticing that he's been acting weird and since I've been cheated on before, I am afraid that I might be right... I know that that same reaction is going to pull him further away from me instead of closer to me... Overall he's a good man.. He cooks when I'm too tired, he takes care of me when I'm sick, ( and I'm the nurse), he works and on a normal basis he comes home. I feel like maybe he's starting to hate me... Helppppp
