How to apologize?

Okay I need advice here.. so my SO and I work at the same place so we are both in the work text message group. Anyway they were joking around about creative ways to deliver our checks (social distancing and whatnot) but then my SO said “I’ll have my secretary pick mine up” and my boss (who has a tendency to make inappropriate jokes anyway) said “oh so is that what we’re calling *input my name* now?”

And my so didn’t respond but I did. I said “*bosses name* I usually don’t mind your humor and the jokes you normally make but do not make sexist jokes at my expense because I didnt find that the slightest bit funny. I appreciate your understanding.” And then no one, not a single person commented again in the group chat and now my SO is saying he hopes my boss doesn’t get mad over it and I said well if he gets mad that I said don’t fucking call me a secretary when we work the same job and same hours then fuck him 🤷🏻‍♀️ but now I’m wondering if I was being too sensitive and if I should in some way apologize for maybe being unprofessional. Because I really could have sent him something in a private message and not the group chat but at the moment I was insulted he would say that in a group message and I just responded right away.

Now I get irritated with my boss often because he’s made stupid jokes before usually about dumb shit like my SO having other women or shit and makes jokes about him being in the doghouse and I do get joked around with more even though my SO and I DO WORK THE SAME JOB SAME HOURS SAME EVERYTHING and it’s like .. I need this job. I need the money. But my boss is a grown ass fucking man and I hate the immaturity but this job is what keeps me providing for my kids. (Well at least before this coronavirus mess..) so someone please help me find the wording I may need to apologize for my “public” outburst. 😓

Update: Gonna keep this short and simple. My boss called me this morning apologizing for his comment and assured me he wouldn’t make comments towards me like that again. I apologized for snapping in the group message however I still told him that just because I work in a male dominated work space that it doesn’t mean I will allow certain jokes to be made at my expense. Or even the other woman that works with us as we are the only two women and the other 7 employees are men. I appreciate the different opinions however I’m no longer addressing the topic with my boss unless it does happen again because this wasn’t the first time he has disrespected me. In group chat or in the work place in front of people. It was simply the first time I stood up for myself. We will see what happens from here. Thanks.

Edit: Also, I’m not seeing where some ladies are saying my SO disrespected me as he never mentioned me by name. My boss did. I did however talk to my SO and tell him the way the jokes were set up it led our boss to it and to maybe not entertain that much out of our boss since it easily led to him disrespecting me again. My SO had apologized when the text happened anyway but I’m not gonna be upset with him when he didn’t really do anything. I explained I didn’t like the way our boss handles his humor with the female employees and my SO assured me he wouldn’t be entertaining that. So as far as my SO and I, we are fine.
