Family and Facebook

So.. I wasn't thinking properly when I saw that my grandma now has a facebook and requested to be her friend.
My dad's mom is on facebook now. Two family members suggested that I be friends with her. I sent her a friend request thinking "Oh she'll see this in about a month. That's plenty of time for me to tell her that I'm gay and that I'm dating J." Boy was I wrong. I got home from school today and saw that she had accepted my friend request and commented on one of my posts about J.
Lucky for me I have a second cousin who is gay and lives in California with her girlfriend/partner and their two adopted daughters. Grandma adores them. I knew she would be okay with me being gay but I just couldn't find the right time to tell her. I'm pretty sure that she suspected though because of all the conversations we had about marriage equality and civil rights (notice I didn't say 'gay rights'. We are not special we are just normal people who deserve the rights that everyone else has).
I'm kind of disappointed that I didn't get to tell her about J in person. She deserves to hear it from me, not from facebook. I guess I just have to deal with it.
I don't want to brag but while I'm on the subject of telling my family, I'm going to say that everyone in my family knows that I'm gay and they are all really cool about it. I'm actually waiting for someone not to be. I don't understand how I got so lucky to have a family who accepts and loves me for who I am. Not everybody has that and I feel so lucky and extremely grateful that I do. I don't have to keep J a secret from them, not that I could even if I had to. She's just so amazing that I have to share it with everybody :)
