We're friends with another married couple. The "OG friends" are the wife and myself, but our husbands got along really well and we enjoy hanging out together.
We're fairly close to them, we've helped them out whenever we can, and we always felt they were a very solid couple.
Until yesterday, when my DH witnessed a massive fallout between them and since then my friend's husband has used him as an "agony uncle".
I thought of messaging her, but decided against it because it would then involve me. At some point the husband almost left, and we did think of offering the spare room, but it would look like we're taking sides when we aren't.
I guess what I'm asking is, how can we stay neutral while also supporting both?
