For some time now ive had suspicions of a friends wife not being faithful. (Not a horribly close friend but we hang out often enough) a couple of weeks ago that suspicion became a reality. Basically I caught her sucking face with the guy I had suspicions about. Im 95% positive she doesn't know that I know.they've got about 6 yrs invested together with no kids. She is very clear she wants them and he is very clear he does also but wants to wait 3 yrs. He wants a promotion that will have him working like a slave till he gets it.ive distanced myself from them a bit and thats been noticed.do I tell him??
