When my brother passed away several years ago his exwife and her husband showed up - her father (a pastor) was the one who did the service and none of us minded!!! His widow (from whom his divorce would've been final the day after he died!) was the most unwelcome person there unfortunately - she would not 'allow' his new girlfriend to come to the veiwing or the funeral... sad... we had her over to the house after and we all sat around and remembered him with her. Glad your situation turned out well.
