Sure. All relationships are vulnerable to cheating. We've had a few same sex couples that I can remember. Some split; some stayed together.
I'm in a small group - I'm a man; my W cheated with a woman.
I'm as sure as I can be that there's a lot of similarities among BSes, no matter what the sexual identities of the people involved may be. If you read a lot here, my bet is that you'll find people thinking and feeling pretty much as you do, irrespective of gender.
And I'm as sure as I can be that all BSes need to deal with immense amounts of grief, anger, fear, shame, whatever....
All I'll say now, since I know so little about your sitch, is to have faith in yourself to heal. I don't know if you'll stay together or split, but I'm as sure as I can be that you can heal, survive, and thrive.
Following the advice above is a good start.
