I really need help

I’m on the verge of a panic attack. Maybe I’m wrong but it feels like my husband talks to me so disrespectfully. I want to just cry because he isn’t receptive if I bring it up, I tried. I told him just a few days ago to work on how he talks to me. He just said ok but nothing has changed. I believe he just thinks it’s all my fault or me.

I have a 21 month old toddler boy and a husband who owns a biz. I didn’t work for the longest time until recently when I went to work for my husband part-time while my son is in daycare. I also manage our home and take care of our projects outside of work like taxes, mail, billing, etc. I’m not on payroll and don’t get paid but My husband provides for all of us. Reason I’m mentioning what I do during the day is so I can have your input when I tell you what my therapist said. We are 2 years married and we have our fights but I’m always willing to look at my side. We recently had an argument and I realize I was wrong but during the argument my husband said some mean things to me. I ignored it and apologized for my wrongdoing. It’s been a few days since our argument and he is still talking to me disrespectfully when I do nothing to provoke him. Today, I kept to myself and took care of our toddler, cleaned the house and didn’t bug him, nag him…nothing! We had a get together with his dad who was a little late and I just said “oh, I was hoping he’d be here on time because it just means we will have less time with him” that’s all I said!!! Meant nothing by it but my husband SO sarcastically said “I can do the math”. This is how he treats me. Passive aggressive remarks, sarcastic, I hate it. So disrespectfully. I make a comment meaning nothing bad by it and he acts disrespectful. I try and stay strong and say nothing but I’m so beaten inside. Curious about what you think My therapist said. She said “We definitely need to come up with a tactic to counteract this because I do see it escalating. I really think a great first step is you finding a passion. If you spent the day doing something that excited you, you would care less about him being a jerk. And he probably would be less if a jerk because he would be less comfortable. Right now, your existence surrounds him so he has tons of freedom to act up because what are you going to turn to? Nothing. It's not ok and you deserve better.” I work for him part time at home and do home stuff. I’m always at home except when I go to the gym and run errands. I thought I was being a good wife by taking care of the home 😢 😢 I do focus A LOT on my husband. He’s my world..him and my son. And he IS comfortable. I’d never leave or do anything. I’m home all the time even work from home. If I tell my husband I feel disrespected trust me it will go nowhere. What do I do? I want to just cry. Do I really need to shake his world and make him feel less comfortable? Please, how do I do this?
