Why not spend my time replying to five-year-old comments?
So Kitty was created by Chris Claremont, who wrote the main X-Men title and some sister books from 1985 to 1991. During his run, he depicts Kitty as bisexual, not lesbian, as openly as he can at a company that had an official no gays policy at the time thanks to editor-in-chief Jim Shooter. The same applies to most X-women he wrote and some of the X-guys. For instance, it's heavily implied that Storm adopts her iconic punk look after a night of passion with another woman.
Kitty's main love interest is Peter "Colossus" Rasputin, but she also has a certain vibe with Peter's sister Illyana, AKA Magik. They're roommates and besties and would die for each other. Towards the end of the run, Illyana reverts back to childhood and Kitty joins a British team called Excalibur. There she forms a similarly close relationship with her teammate Rachel "Phoenix" Summers. Things had gotten more liberal at Marvel and Claremont wanted to make them an official couple, but sadly we live in a fallen world. Some of the early issues of Excalibur start gearing the audience up for this with panels where Kitty's getting flustered looking at attractive women. The Peter Wisdom stuff is from Warren Ellis's run in the 90s.
