A bit complicated but me and DH are best friends with another couple. We socialise together a lot, go on holiday every year etc so we are quite close. In the 10 years we have known each other Me and my friend have never discussed her relationship or marriage (so I don't know her feelings on any of this). They have been together 25+ years and have two teen dc's.
They have a bit of an unconventional relationship in that they have sort of separate lives, they are more like friends than a couple. They do things together when it involves their kids or a wider group of friends, but don't go away alone or even have lunch/dinner alone together. They don't do things together, they don't have any shared interests past the kids. There is no public affection (which I know isn't everyone's cup of tea) I don't go snogging my DH's face off, but will stand next to him, touch his arm/hand etc. Just small things.
The H of the couple has mentioned to DH when they've been on their own, that they only have sex once a year. But they always seemed happy, they've been together for nearly 30 years so must be doing something right!!
But recently, the H has said a few things to DH that he's now told me, more because he's worried about his friend (thinks he may be depressed). But he's said a few times that now the kids are older he's not sure he can be bothered to stay with his DW, his life is boring now. But said he's not sure he can afford to leave (house not worth loads, not enough to start over again). It's probably better to stay and be unhappy than it is to leave. But DH said last night he was talking and he's worried that his friend is thinking of having an affair. There isn't anyone in the picture (that he is sure of) but he was saying he's had offers over the years from women and he's always been faithful. But if the offer was there he wouldn't hesitate in taking the offer now.
Do I tell my friend? I feel awful knowing all this and not saying anything. But could it make the situation worse? I said to DH that it sounds like a mid life crisis almost. Should I keep my nose out or let her know what he's said?
