I tend to agree with Divine. If I caught my soon to be husband talking to women on Tinder, it would be over for me.

The problem here is that trust has been violated. It doesn’t matter sometimes whether no sex was involved. What does matter is the violation and the breach of trust. When that’s been broken, it doesn’t always come back. Some people can salvage a relationship, but the trust factor will most likely be a problem. If it were me, I’d always be looking over my shoulder.

Couples therapy is not always the answer. His wife may want to divorce and that’s her choice. He broke the trust. We cannot assume that no sexual conversations occurred. I don’t believe the OP has disclosed the nature of these conversations or how far they went.

Perhaps it’s cultural that she relies on her family for support. Perhaps she’s just very close with them. I am very close with my own family; they know of most everything that happens in my life.Perhaps they didn’t need to be involved in the confrontation, but maybe she needed her family beside her. I don’t fault his wife for talking to her family about their issues.

What I do wonder is why did he talk to other women on Tinder and what was at the bottom of doing so? To the OP I ask that question. Perhaps it’s something you can’t answer but it may be good to understand why.
