Just go for the family, as you suggest. Don't ask your wife where she wants to sit. Just let her sit where she wants. Be friendly, but that's all. Don't second-guess why she's using this opportunity to contact you. It's irrelevant and likely she won't tell you and she may feel differently tomorrow, so don't read too much into it. Just be there for your friends during this difficult time and make that your focus during the services.
