I'm a Roman Catholic who does not believe in purgatory. I'd like to think that most of my loved ones have gone to heaven. If they haven't, I certainly would not know now and when I die, it wouldn't matter then. My father died a few years ago and I just take it for granted that he went to heaven. Don't spend too much time torturing yourself over this more than the natural time of grieving allows. God bless.
Don't think of purgatory as a "place" so much, or an an alternative to going to heaven.
Think of it as the transition from imperfection to perfection, it is the putting on of the garments in preperation to entering into the feast.
