Invading my privacy

So my partner went through my phone, I must’ve been asleep. But today he woke up mad and when he left to work began texting me very passive aggressively about me talking sh*t about him to my friends. Which in my defense I was venting about our arguments, he took it offensively bc he’s been rude and borderline abusive. I’m also dealing with potentially losing a good job and he’s over here expecting me not to be stressed out when I have a ton of chores, 2 toddlers, I no longer have the patience for him. I’m full of rage inside but me losing my job could put a financial strain on me. I’m at the point where I need to seek mental help for medication to calm my nerves.
