It's not cheating yet, but it will be soon if you act any further. It doesn't matter the gender of the person. Take away the gender issue and just call them a person. Do you really think the person you're getting married to would like you involved with another person? Sex is one thing and definitely wrong to have sex with someone else while you're engaged, but a mental connection is even worse. A body definatly has gender, but the mind is just a mind. Cheating is Cheating. You're going to do what you want to do, but don't lie to yourself, I get the feeling you all ready know this all anyway.If your bi and engaged is it ok to have feelings for a girl?
Why is this any different than if you were hetero?

If you are engaged you can't act on feelings for someone else regardless of gender.

Cheating is cheating.
You can have feelings if you are engaged but if you act on them then its cheating. If your fiance knows you are bi then it would be fair to let him know. There are some couple out there that are committed to one but play with others, if you catch my drift.
in ur sitch it would probably be best to try and concentrate on ur fiance unless your totally in love with the girl more than the guy in wich case u should breK IT OFF
