How much is too much

How much stress is to much stress.. Yet again my husband and i got into an argument over something petty. Me asking if i could take the car at 4:30 in the morning tp take myself to work so we didnt have to wake up our 2 year old. He got pissed and we argued. So i asked my female manager for a ride. She had tp be in at the same time as me. And when i got off work at 1 it started all over again because some random guy messaged me and i wanted him to see it. Welp it all got turned around on me. "You probably set it up, you probably want to be with the guy, youre just trying to piss me off" well im not i dont like to argue with him at all. So my question how much stress is to much stress for the baby? 24ws 4ds
