You will be nervous and that's ok, keep your conversation strictly business, don't let her suck you into anything else. You will feel a sense of relief but also sadness as well, morning what was or what could have been. Take a day or two for yourself but then get back on that horse and ride!
When my XW showed up for court she had no make up on and looked tired. I could tell she was sad as well, I tried to hold it together but started tearing up when she was reading from her script. She looked over at me and then her voice started to crack as well. In that moment I knew she wasn't the ice princess and at least felt something.
Just know you that you will be ok....take your lessons learned and move forward.
