You have to trust her on it. That's really all you can do, right?
The other option is to ask her about it everyday and if she's being honest about it and nag her to death ..... I know you don't want to do that and probably know it wouldn't turn out well.
Let go, Let God.
Get back in the steps. Focus on you.
