Nervous

My fiancé is at his mediation with his ex right now. I wanted to go with but no one is allowed to be in the room only him and her. I do not trust her at all. She’s pulled a lot of shit and has made our relationship hell for a bit. When she gave birth, the baby was in the NICU for a week and she would text me saying they hooked up. She also texted me saying they hooked up when my fiancé and I had a huge fight. Basically any time they’re alone, I wake up to a text saying they hooked up. I’m so done with that bs and I told my fiancé last night. I just feel like I’m going to have some kind of text tomorrow. I don’t know when the mediation is suppose to be over and who knows what’s gonna happen after.. sorry I just had to vent right now because I’m freaking out a little bit. All I want is to have our time with his son and not have all this drama.
