Impotent or cheating? What to do?

I'm trying to help a friend, she's been having problems with her marriage for a few years now.
Her husband doesn't want intimacy, they haven't have sex for years. However, she found out two years ago that he was having an affair with someone from work. At that time she decided to give him a second chance. Two years passed, and still no sex. I feel that my friend has changed, she became sad and anxious.
Last week I went to visit her, and I heard them talking. He was speaking in a very rude way to her, like he was annoyed. She told me he keeps saying that he loves her very much. But he refuses to even speak about the intimacy problems.
My friend came to me asking for advice, but I really don't know what to tell her. Last time I told her to leave, but she decided to give him a chance. Is he cheating again? What should ia tell her?

Thanks every one.

I really don't know :/ but if I had to take a wild guess, I'd say he's probably cheating again.. but that's just an assumption.

Idk.. can't you help her to "investigate" or something? I'm sorry I can't be more helpful :/

Thank you Mickey,

It is a very strange situation. I don't know what to do and say. It is also difficult to try and help her to investigate him. I might put myself in a problem.
I was looking at his Facebook today, and I noticed that he has only picutres of himself to with his family. Not pictures of them together, although they travel a lot. The guy has a serious problem, that's a fact.

I would caution you to tread very carefully, nobody ever knows what really goes on within a marriage, if you get involved in trouble between them you may inadvertently make matters worse.

I think the best you can do is be good company for your friend, in that way you are helping her be happier in the time she is with you. Only she can decide what to do about her marriage, you might want to reassure her you are there for her whatever she chooses to do.

You're very right. Thank you. She's will stay at my place for a few days

I would advise my friend to first address the lack of intimacy, not assume he is cheating. There is a real problem if there is no sex in a marriage (unless there are health reasons). They need to talk it out and make some decisions to spice up their marriage. If there are deeper issues, they should get professional counseling.

It's not your place to say if she should leave him or accuse him of cheating (even though he may be cheating), but I would encourage her to try to first work things out with the help of professionals (perhaps counseling or maybe even a Viagra Rx from a doctor if there is lack of sex drive).

You've asked if he's cheating again.

Reality is, none of us here can answer that question.

In terms of what to tell her; I'd say be upfront that you don't know what to say; but you're there to listen.

Remember she's the one that lives with the consequences.

We had a long chat today. She said she tried anything. Last time they try viagem, but she found out he was using the prescription with his mistress, not with my friend. I don't know what to tell her

Very true. I will listen, but will try. It to get too involved. Thank you.
