when giving advices to a friend....

The best thing you can do is tell her to be honest with her husband. It is something they need to get through together, and no amount of trying to find something better online is ever going to fix her marriage. Rather than trying to avoid the problem he needs to be made aware of it and then as a couple they need to find a way to resolve things and hopefuly move on together. If she decides to go after this guy it will probably be the biggest mistake of her life, throwing away everything she currently has on the offchance that this is a genuine person, which on the internet is never a garenteed things. She needs to realise just how much of a risk she is taking, because 9 times out of 10, the type of choice she is thinking of making backfires and ruins many many lives.

You can't advice her to do anything. She is in a rut, her husband is probably great but after being married things get stale, and here is this guy online who just seems so perfect and pays attention to her, and really listens to her... It's a situation most women find themselves in at some time. If she's going to do something like have an affair nothing you can do will stop her. What's the saying "the grass is always greener on the other side" it's so much easier for some random person online to fill in the gaps and simplify things and give us what we want. They aren't there for the day to day crap. They aren't the ones we clean up after, or fight with, because they are separate from all of that, and that as much as anything else is why so many women have affairs. She's going to make her choice, all you can do is stand by her and either help her fix her marriage or help her end it. Hopefully she's smart enough to do one or the other and not just sneak around.

Tell her that she's making a huge mistake in interacting with this person she met on the internet. Marriage is not something that you spit out when you finally get tired of chewing it. A couple need to work hard to be able to attain a happy marriage. They should go into counseling for them to have a more meaningful and enjoyable marriage life.

I think you advised her right. She really needs to think things out and realize what she is giving up she only knows this guy on the internet and who he is in real life. She cannot take back what she does if she leaves her husband for this guy.

Well if your friend does not try then you might want to just give up or if she try you just might get it done after all.
