What if my wife sends ambiguous messages to other men?

Now that we have found out, we must beat about the bush.

Let her know that you have noticed, and let her restrain herself.

Maybe she just started. It depends on her.

Or you can care more about your wife.

Let her know that you love her and care about her.

Maybe she cares about her family, so she doesn't fuck other playboys.

You have no evidence at present, so don't rush to fight.
