Tom Bridegroom was in a committed relationship with Shane Bitney Crone for 6 years, they started a business together, bought a house, and were the ideal couple until an untimely accident took Tom's life and the violent/threatening reaction from Tom's family to him coming out resulted in Shane being totally cut off from Tom after his death. They didn't have wills and couldn't get married, so Tom's family was able to take all of Tom's stuff, the hospital denied Shane access to Tom's information, and Tom's family threatened Shane if he showed up to Tom's funeral.
From the family's perspective, Tom has been largely secretive for the past 6 years, began a business, bought a house, lived with another person, and apparently did this all without anyone knowing he was in a relationship. Considering the relationship was such a huge part of his life (started a business together), Tom could not have had much contact at all with his family.
The family essentially lost Tom, long before the accident and death.
The family is going to be angry and hold resentments regardless if Tom was in a relationship with a man or a woman. It takes time for individuals to process all this information. It is a slow process.
This is far from an ideal couple. The ideal couple is a relationship along with supporting families who are a part of each others lives. That was not the case here.
