What do I do?

I don’t understand what to do,
My girlfriend wants to figure out if she’s bisexual,
And in order for her to do that,
She has to kiss a girl,
But if she does that the she would have to cheat on me,
Because I’m not going to break up with her,
Especially since we just got back together.
But I don’t know what to do,
Should I break up with her to see if she really is bisexual?
And hopefully get back together with her after she figures it out,
But that’ll take at least a couple of months,
Or do I not break up with her and let her wonder until we break up.
I don’t know.
Can you please help me?
I know this site is for poems,but no one will help me,
Maybe someone who has been through what I’ve been through could help me.
Please if you ever been through this,
Please comment.
I don’t want to loose her again,
But right now it seems like the only way.
