I agree with this, but I do see both sides. I feel for the friend. She's entitled to happiness. No one should ever tell her to live a lie. But regardless of the reasons, divorce is quite devastating to the people involved, especially the children.
And to Disney Doll, in defense of your friend, it sounds like her "this is who I am and you should be happy with me" was less of an "in-your-face" statement, and more of a defensive move. She was just beginning to come to terms with herself, but obviously not quite there. If she wasn't entirely sure of where she was herself, she probably expected that she'd get some resistence from others. So she came out swinging, so to say.
The coming out process is never easy, but it's definitely a 2-way street. As I said before, the person coming out should always remember to GIVE the same respect and understanding that they expect to GET.
Also, to Disney Doll. I just went back and re-read what you posted before about your friend. I can give a little insight into what your friend was going through when she first came out. It's sort of like when you're young and first begin dating. You feel uncertain about yourself and your place in your surroundings. Coming out "later" in life is a little like having to re-do your adolescence. It's sometimes a rocky road, and you tend to surround yourself with people who are going through or have gone through the same thing you're experiencing. It's all so new, and you feel most comfortable with those who know what you're going through. I know it had to have been painful to lose the friendship you had, but she most likely had no intention of hurting you...It was more of a self-preservation of sorts.
