Is it OK to have non-sexual affairs outside of marriage?

[Guest Amrit Gill]

I want to help my best friend, I want to know if Gurbani has a tukk or explanation about situation like this: My best friend recently told me about a guy she dates online, there is no sexual relation and nor she is thinking of doing anything like that, I do trust her in this. She has been married for 21 years and have 3 kids. According to her,  her married life is very normal, good, no fights with her husband but she clams that she have found a person who she can talk about love or share things (again, I am not talking about sexual related things). Also she says her husband is simple guy who doesn't think too much about emotions of any kind so he have never shared anything like that. She says it has always been hard for her, to open up with him, she doesn't want to ruin her family. I think regardless it is wrong to cheat. I don't know, what I would've done if I was in her place but it makes me very angry and I want to explain her that this might be wrong. But at the same time i'm confused because "God does everything for good cause". I want to help her (or help myself too, if i wrong to be angry on her) So what does Gurbani have to say about this? Thanks in advance.
