Quite frankly, I think the only response you can give her is "Fuck off Mom and please don't ever contact me again until you can be a reasonable human being who accepts who I love and who I am with."

I can't live your life for you, but in my opinion, if you go home for Christmas, you are a doing a HUGE injustice to Kellie. We won't get to see you at all if Kellie is with you. What a bunch of horse shit. But if you were with a man, he would be welcome and wouldn't take up your time? The ability to hog one's time comes from having a uterus?

I'm a very firm believer that family is what you make it...not necessarily who you are related to by blood (if you happen to love your blood relatives, it is a great bonus) Kellie is your family. Spend the holidays with her.
