Husband said he laughs at me with his boss behind my back

Husband and I have been married 6 years and have one year old triplets. My mom takes them one Sunday a month and then brings them back to me Monday morning. I’m a SAHM because daycare for three one year olds is astronomical so we decided together I would stay home.

The kids went to my moms today as usual and my husband and I were home. He wanted to spend the day deep cleaning the house which I was fine with (house is always very clean but we deep clean like this once every three weeks).

He was a huge dick the whole day about cleaning. He would point at what he wanted me to clean so I would start and he would stand there watching me judgmentally, telling me what I should be doing all while occasionally glancing at Facebook. Eventually at one point I got so annoyed I told him to go to another room and not watch me as a I clean if he wasn’t going to help. That made him mad so he told me wanted to supervise while I was cleaning to make sure I did it right and up to his standards. I got through the rest of the cleaning then started to get stuff ready for the week ahead.

I did his laundry for the week and I make his lunch every night for the next day so as I was doing that he told me not to forget a fork and a knife so I could cut open his avocado (he likes to eat them plain). I apologized and told him I knew I had forgotten it Friday and I wouldn’t again. This is the ONLY time I have forgotten to send him with a knife and fork. He then kept insisted I forget it EVERY TIME so I jokingly called him a “little liar” and laughed thinking he was just joking around. He then got very serious and said very seriously “you actually do forget them every time you little bitch and I know you do because my boss and I laugh about that and you every day at lunch time.” I was furious. I instantly stopped making his lunch. Packed a bag and drive straight to my moms where my kids already were and now I’m evaluating options. He told me to go and went straight to bed before I had even left as if he regretted none of what he said. I want a divorce. My sister thinks maybe he had a “bad day” and I should give him a chance. This is INSANE to me. He openly admitted to talking about me in a bad way to his work friends and he called me a bitch and has absolutely no remorse about it. I’m meeting with a lawyer on Wednesday to go over my options. What is your opinion on this? I’m not being dramatic right?
