I'm so sorry to read of everything you're going through. If you read my thread you'll see some similarities. I'm still figuring things out on my end regarding distancing but it seems you're on the right track. I personally think the focus should be on keeping things as normal and peaceful as possible for the child. That might mean a polite "hi, how are you? Nice to see you...." When your husband comes to get your child or a simple exchange without unnecessary questions or discussions.
