To the OP: of course it’s shaken your world. My heart aches for you both. Love her like crazy. In any way that you can without totally alienating her, urge her to celibacy. All sin has an addictive quality to it - the more we indulge a sinful urge, the more we want it and the weaker we get against it. The less she acts on this urge, the better. Being homosexual is not the end of the world, but it is still a very hard way to live, even if the world is applauding that choice like crazy. It really would be wise for her to be celibate for five years or more, and to use those years building herself up in other ways, and that would give her time to see if this is real and permanent in her life, or if it was just passing. Our culture already despised celibacy before the beginning of the LGBTQ movement. The LGBTQ movement has only made celibacy even more despised. But it really is the path of greatest wisdom.
