Some of these responses are really quite odd and very dramatic. Not going on this trip doesn’t mean her friendship group is over, she doesn’t need to find new friends, and I’d bet good money her friends don’t think she will try to steal their husbands either.
op, simply four months in this is very awkward for everyone. And they are still finding their footing in how to handle the new dynamics.
im surprised you’d still want to go on a couples break with your ex., that would be incredibly awkward, as evidenced by him saying no, i think you’re thinking more about the fact you want to go rather than the reality of it. Everyone else is thinking of the reality of it.
we have a couple in our group who divorced, it was incredibly awkward, so we took it in turns to invite them to group events, as in one came to one, the other came to the next and so on.
The male wanted us to invite them both together to events, saw no reason why they could not just both go, and the female was a complete no to that , but he wanted them to get back together and she would rather have chewed her own arm off than get back with him. It was pleasant for the kids between them,
we did do a weekend away with them both, at a festival, not long after they split, as the tickers were bought and paid for, and it was a terrible idea, never to be repeated, as he kept trying to be very friendly to her, whilst she wanted him to fuck off to the other side of the moon, so we ended up spending a lot of time in little groups so they were apart.
