My advice to you is to stay out of other peoples drama. What has to happen here is some serious communication between these two individuals, difficult questions have be asked and answered about the woman on his cell phone. If they can't communicate with each other and she is resorting to a key logger because she does not trust him, the marriage has already failed.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
