My husband has a treaty message on his mobile phone. We have been married 14 years.

Definitely the rhythm of extramarital affairs. Maybe it has happened, maybe it is happening. It depends on your attitude anyway. If you are ready for a divorce, you can investigate and pursue it. But once it is confirmed to be true, it will be passive if you don't divorce. Even if the other party asks you to forgive you, you will suffer forever if you don't get divorced. So if you don't want a divorce, you'd better play dumb. This is to hide people's eyes and ears, that is, if you think you may have an affair, just pretend not to, so that you will feel better and get along without embarrassment. Anyway, make up your mind.
