A dad-of-two started drifting from his wife 17 years into marriage.
She was annoyed he didn’t do “little things” for her, like planning fun trips abroad or romantic dates.
And as the pair drifted, a new problem arose in their relationship.
The husband’s friend started crashing on the couple's sofa as he was going through separation.
Sparks started flying between him and the unhappy wife, which raised more questions about the marriage.
So in a bid to save his relationship, the dad gave his partner permission to sleep with their mutual friend.
On Reddit, the husband wrote: “Lately a close family friend starting going through separation.
“We let him crash at our place for a while. Little did I know, he was flirting pretty hard with the Mrs.
“For a while she was not going for it, but eventually he won her over.
“I found out that she had real feelings for him one day, while assuring me that it was just a silly crush.
“I told her I would do whatever it took to make her happy. 24 hours pass, and then she went right over to his house.”
Even though the husband gave permission for his wife to sleep with someone else, her attraction didn’t end up being satisfied.
The Redditor added: “Interestingly, he ended up turning her down because he got tired of chasing her and found someone else.
“She was p*ssed and really only wanted to talk to me about how he’s so screwed up for not taking her.
“She’s not at all upset about what she’s doing to me or the family.
“She’s only been willing to talk about lawyers and turned down any peace offerings from me.
“She’s also not willing to do counselling. She says it is too late that since she already checked out of the marriage years ago.”
Devastated that he couldn’t seem to make the marriage work, the dad asked Reddit users for advice.
He wrote: “I’d still like to fight to keep this marriage together. If there weren’t kids involved, I wouldn’t be playing doormat.
“She was the love of my life. I can find other people if I have to, but I love her and I love my kids…
“I know I’m not perfect, but I don’t really buy into the notion this is all my fault. I’d really like to hear your thoughts. Thanks in advance!”
Sadly, the majority of responses told the husband that his marriage sounded like it was over.
One responder wrote: “There is no part of this that gives you the slightest hint that this marriage can be saved.
“I held on much longer than I should in my marriage hoping he would come around. He didn't. Start detaching from her. It's a very painful process.
“You'll be very sad and then you will get p*ssed off. I'll let you know what comes after that. I'm hoping it is peace.”
Another said: “Dude she sucks as a person. You can’t fix that. Why would you want her besides to give the kids a family?”
And a third added: “It is over, once you face that fact you can move forward.”
