Freaking OUt about school function with the STBXH

So, I have been trying really hard to stay dark to STBXH. I don't talk to him unless it is about the kids and that is it. If he asks me about financial info b/c we can't agree on child support and I am waiting to go to a lawyer until I get the funds together. So, my daughter starts kindergarden and I am so emotional about that b/c my baby is growing up but I am also stressing about having to do all this with him. I asked him if I could take her in the morning and he could pick her up and he wanted to be there in the morning, which I understand. Then I found out about the kindergarden orientation for the families and the new parent meeting the first day of school and I am freaking out. I am an emotional person when it comes to my kids, so I am going to be emotional to begin with and now to add that he will be there with me through all of this, I am really freaking out. I know that this sounds so silly to some but for me, who struggles when I am around him but better when I don't have to be around him at all, this is a huge deal for me. He knows a lot of people in town b/c of his job and we have always ran into someone everywhere we go. At our last family function that we had to go to together we ran into some guests that he knew and I got bombarded with how questions about how it was to be married to a bartender and someone so great, blah, blah, blah. He was standing next to me and I just froze b/c I didn't know what to say. Has anyone else had to go through with this and how did you answer questions and what did you do. It isn't like I can avoid him. I know I can introduce him as my daughter's father but how do I hold myself together on such an important day for my daughter. She is the one that this should be about and I can hide my tears and blame that occasion for my tears but I need to keep my mouth shut about saying anything negative to him. I just don't know how to react or what to do or how to stay away from talking to him about anything outside of her. This is two weeks away and I am trying so hard to just plan for anything and everything so I don't do anything wrong ... does this make sense, lol?
