What is a man to do when it comes to serious relationships? Either she's going to cheat on you or she has already cheated on you. So how do you go about dealing with that fact? It seems to me you have only a few options:

A) Know that she is probably cheating, but just hope you don't catch her (ignorance is bliss)

B) Constantly spy on her

C) Constantly accuse her of cheating or

D) Never get into a LTR

None of these options sound favorable.

Edit: I forgot to add, I am happily married. This was just a thought that came across my mind. Dated around a bit and I have seen what others have been through to know I got VERY lucky with the woman I am with.
