If it makes you feel any better, I lost my brother last year and his wife demanded that only his brother's, mother and kids (the kid's mother was not allowed as she said it was disrespectful to her as she was the current wife) were allowed at the funeral. She said it was his wish but we all have any issue with this as he committed suicide and they were only married 11 months; we all doubt he even said it. She made it so clear that she threatened to take his creamated remains if more then the people who she said showed up.
So we scheduled a second "service" an hour after the one she put restrictions. She was leaving as we were arriving back at the cemetary, she turned around, parked her car within eye shot and got in and out of her car, pacing back and forth, etc. It was so sad and pathetic. Many of the family members who were not invited to the first funeral were very hurt by not being able to be there, which is why we scheduled the second one.
