MUST READ: When your sins puts your child in harms way

I have been sleeping with my brother inlaw who is living with us and schooling.
He is in the university.
We have been doing this for 2 years now and I have even aborted a child for him . I saw him touching my daughter today , he has already removed her panties and was about to put his finger in before I ran in and started fighting him.

I am so ashamed I can’t even tell anyone or my husband.
What do I do ? How do I get this bastard out of my home without him messing my marriage up ?
What advice should be given to this lady?? Please share your thoughts.
