She's playing you for a fool dude.
She's already been fucking that other dude and she just used you to get permission, so to speak. Now that she has it, do you think she's going to ask you before she fucks him again? Keep on dreaming that dream, let us know how it works out for you.
It's time to be a man and put her out like the trash she is.
Or, you can let her drag you through life by your dick.
Your call.
