A small group of husbands colleagues have become firm friends with him over the last 12 months - in particular 3 females. He now regularly meets up with either all 3 females together, or separately with them for lunch dates/tea and cake/evenings out/tea in their homes.
He has refused to introduce me to them when I have asked. He says they are just his friends, not our friends.
So I either stay home with the children (we have no family or childcare) or he arranges his meet ups on days he knows I'm at work - therefore I can't ask to be included.
I've heard through mutual friends that two of the women are questionable and not to be trusted around men due to them both having affairs with married men. He has defended them when I mentioned this. My mental health has suffered as a result and I feel lonely/unwanted.
Not really sure what to do from here, just looking for advice or a hand hold I guess.
