Ok, so I am wondering what people have done in this circumstance...........

A friend has been married for a few years, loves his wife, no fights or arguments, things are good and both husband and wife are working towards a future.

Another woman has come into the picture. From what I can tell there is sometype of bond between the two (married guy and new woman). There has been no intimate moments, no making out from what I've been told. Just hanging out, texting, etc.

He's talked to me a few times about his feelings for the new girl, which seem to be strong, but I continue to tell him what he already has and what he would lose if the relationship became serious.

I don't want to see him divorced (if it came to that) but I feel that maybe there is something that I'm missing or have overlooked
