Well at first I was going to say that even if nothing romantic takes places, his involvement with his friend is excessive, inappropriate and way over the top.

But then I looked at your previous posts and it’s quite obvious that your husband is sexually attracted to men. It could be just a fantasy of course and he would not actually pursue a man in that fashion. But it could also be that he is interested in men more than just friendship and more than innocent fantasy.

Now we can’t help who we like or attracted to but we can control our actions. As a married man if he wants to be that involved with another person (a man or a woman), he’d need to leave this marriage.

Being bisexual (if he is) doesn’t mean that a married person would pursue same sex partner while married or that it’s even appropriate thing to do. Most certainly sharing your finances or sex life with others is completely unacceptable. Wondering how often does he see this guy or it’s all just over the phone?

I recommend marital counseling. If he refuses to go, see a therapist yourself. But it’s just can’t go on like this.
