This is about my Brother-in-Law (57) and Sister -in_Law (36). They are having this problem and my Sister-in-law is looking to my wife and I to help her solve the issue.

The issue is:
He is spending way too much time chatting to "friends" in an internet chat site, like up-to about 3am each night. He uses words like " I love you" and "I can't sleep because I can't stop thinking about you" when chatting to his mostly female friends.

She says he is "cheating" in a fashion ( I agree ).

He says that the chat is empty and meaningless

She accessed his email and found letters worded similar to the chat ( above )

He now changed the password to the email and she thinks there is something more to the whole issue and thinks he is hiding something.

Does anyone have thoughts on the matter.
Please help.
