Brother, you have been given an immense test. I surmise that if you pass this you will no doubt get one of the highest places in heaven. Talk to your local Imam and if you can't do it like that, then say it is your friend who is having this problem.

It is already a good sign that your prayers are working and you have not acted rashly like she did. Keep it up and it can only get better and keep your daughter in mind.
