what should my friend do?

i do not what to say, I really have no experience in such situations. But, I would say that the first thing she got to do is make sure that happened. she must be 100% sure that his husband is in an affair with another girl before making any step. if she is 100% sure, I think she can ask for the divorce.

My hubby had an affair, about 2 years ago now, we have four children. His affair lasted for a year, it was the worst time of my life, but we are still together. She has to take time over this, she has to consider and think about everything, she has to think how she feels about her hubby. If she stays with him, she has to know that she really loves him enough to stay with him, and she has to be able to move on from this affair, if she thinks that she can move on from it then that is fine, but if she thinks that she will hold it against him for the rest of her life then she should leave, because it won't work. I can honestly say that when I decided to stay with my hubby, I knew that I could move on from it, and I have, do not get me wrong, it still hurts, very much some days but I never throw it at him in an argument. If a couple stays together after an affair then they both have to wipe the slate clean to do so. Also talking, there has to be lots of talking, no matter how painful, this helped me a lot, being able to understand and know all the gory details no matter what. I really really hope that your friend is ok, I know how painful it is and I know what she is going through, but tell her not to rush a decision, and her decision must be her own and not made for her children or for anyone else. Tell your friend to take care and I wish her well.

How sad for your friend some people work though things like this and all is well, some others it does not work out. For me if my husband went with anyone else we would be finished, as I could no longer feel the same for him so there would be no point in being with him I would no longer love him. Shame for their daughter.
