Sorry I'm not much of a writer, but would like to genuinely get feedback to understand and work on my marriage.
While having tea/buscuits my wife and I were talking about the potential new furniture. Throughout a movie my wife was scrolling through her phone so at the end of the movie I asked what's going on and if she wanted to talk. She spent the next 4 hours just mouthing "*new furniture*" and I said no, then started her avoid the conversation as I knew it would lead to squabbling. In the end I engaged as I felt we were not going to go to sleep until it happened. It was the wrong decision.
The next hour we were arguing about the cramp-ness of the apartment if it was added. Then new points started to stream in about future children, bedroom layout, statements of "haven't slept since we had a child", and why I made a moment to her parents that she "didn't seem to want to work anymore". (According to her this was a lie, and she only said it to vent to me regularly because she's stressed about her job. For me I've told her she didn't need to work since we're financially stable with my income.)
That night I woke up from 5am and was thinking about the argument and how we had agreed as a new year's resolution to be less petty. By 7am my son woke up so I made him breakfast (pancakes & cereal) then took him out for a stroll. I wrote a message to my wife saying something along the lines of: Taking baby out, sorry she's tired/stressed and offer to take our son to a hotel so she can rest, and hope we can work on being less petty to help our relationship. Immediately there was an angry reply saying I was being petty and I don't get her points. I try to explain I was trying to help. It didn't help the conversation so I just left it at "anyway have a nice day".
By 11am I returned home and saw my wife was still in her bed looking at old videos of our son so I took out the washed clothes to hang them. She came in saying "don't touch it, i'll do it" so i silently waited for her to sort through and get her approval it's ok to hang the clothes. After hanging the clothes I vacuumed the apartment and i heard "he's eating" so snapped "sorry usually when I'm cooking you're vaccuming, but I'll stop". This was again a mistake and it led to a heated argument. In the end she was folding some of the dry laundry so I took our son to my desk to look for a hotel room. She said she didn't want me to hold him and tried to take him back and i said "no", she grabbed again so I let go and she goes "i'm calling social services because you yelled over his head and cussed".
In the end we argued again and she agreed to not call if I put him down, but seriously what the #(@*! is this.
Am I delusional and totally in the wrong? What am I supposed to do?
[Edit 1: shortened to be more to the point]
[Edit 2: she is now saying she wanted to call social services also because I said I want to kill myself around her]
