Welcome to the site and forum and glad you could make it! Really sorry
you are catless -- don't know whereabouts you live, but there are prescription medicines your gf could take, like Zyrtec, that would enable you to live with cats...you may want to visit the health issues forum here as well, and read more about people living successfully with cats even when they have allergies...
I LOVE cats and have lived with 'em all my life. Currently I share life with 9! rescued, indoor-only, spayed/neutered adult felines, who are my life. The few times in my life when I've been catless have been the saddest and loneliest times of my life, no matter how much was going on in my social life otherwise...now, I couldn't live without cats in my life! I love looking at pix of them, but it's just not the same as stroking one, hearing the purrs, looking into the jewel eyes, admiring the beauty and agility, and well, just loving living with cats!!! So for your sake, I sure hope your gf is able to find a way to live with cats, too...GOOD LUCK!!!
