I opened my boyfriends emails....?

Sorry to say this but do you really want to committ yourself to a life of suspicion and lack of trust, because if he's doing that just now, you can guarantee a ring on his finger will not make one bit of difference. I think its time for you to wake up and smell the coffee, he obviously cant be faithfull to you and it doesnt matter if its male or female, you will ALWAYS doubt him now. Is this any way to start off married life? !
