New here but learning slowly. Advice appreciated

Journaling

H flew out of town two days ago. This is the trip to do contract work but also where the OW lives. He stopped by the house prior to leaving to help D with some stuff and I wished him a safe trip. He still doesn't know I know about the OW so I didn't want to wish him a PLEASANT trip or PRODUCTIVE trip or anything that would get him mind running. He texted me to let me know he landed but I didn't respond. It wasn't a question and I didn't really feel like responding.
Didn't hear from him until he decided to call me today. D and me had planned to be at our rental house today doing some last minute painting. He called to see how everything was going. Seemed strange to me that he'd call but I keep reminding myself (MLC!). I updated him on the house and asked how he was. He went on at length about the job etc etc. Half made me wonder if I had misinterpreted whether he was having an A with the OW but then I remembered (believe none of what they say and half of what they do). Especially when I remind myself that it's only been 5 days since he requested starting the legal separation process.
I continue to GAL. One main obstacle has been scheduling my work days around D. Normally, I could count on H picking her up from school on days that I work late. Even though he has continued to do so, I don't like having to consult with him about my schedule anymore. So I'm working on building contacts with other parents on getting her home. If he offers to pick her up then great. But otherwise, I want to make my own schedule without NEEDING his help. And on a fun note, I've signed D and I up for a tandem hangliding event next weekend. Should be fun!
