You know what - just ask. I think you have to, otherwise it will eat away at you. My daughter has a large family of in-laws living nearby, we tend to get forgotten, I fully understand why and how, but I know she loves me. She forgot to invite us to my GS's christening until the day before, when her MiL asked where we would be staying, it was too late for us and to be honest, it would have been a real pain to fit it in at the time. It would have been nice, though, to have been asked. Three years later she almost did it again, she has never had us included in her social life so didn't think, that was all, and she is very busy with two jobs and studying law and two small children. I asked how her brain worked to forget us in that way, and she said that when she thought about it, her first thought was who would be the most annoyed if they weren't asked! I wasn't annoyed, just surprised, so she was right.
