I know about the whole denial thing. My best friend who is gay his mom and step dad were in denial for a long time. At first they thought we were dating haha, then his mom found out kinda like Diane but through letters instead of some blogger and the internet. She threw my friend out of the house so things weren't so cool for a while and I hated his mom for doing it. Now their close once again so time does heal and once acceptance is there at the end of the day they are still the same person you've always known.
