He does not want you to tell his family b/c it will be even harder for him. That is part of accepting responsibility. You tell who you need to tell to make sure you have a face to face network of support for yourself. You deserve that.
I am glad you have different meetings in mind, many times it takes going to a few before you find a group you click with. It's good you already know that. I also think you are taking steps to educate yourself, which is a great thing.
Many hugs to you. Above all else, you are not alone!
