Obviously you are fucking 15 and also no basic idea what you are speaing frankly about.
No matter if shes gonna or otherwise not, its not necessarily their destination to inform their friend is spouse is cheating on him. She should really be telling him and she wont make sure he understands then possibly fundamentally the friend could make a move, but this is not some highschool relationship where slut 1 cheated on bro 1 with bro 2 and bro 3 informs bro 1 about any of it.
To begin with you do not understand that about her. You’re probably appropriate, but neither of us understand her at all, therefore we cannot be yes.
Next, perhaps which is a good addendum since well. OP, obtain the details. One of the ways or another learn all of the facts while making yes you can easily show them to be, in order for you can show him the truth if she lies. But i believe it is vital to provide her, their spouse, the chance to perform some right thing, to make certain that if she does not, she’s got simply no protection.
