How do I Prevent my Sister-in-law from Destroying my Marriage?

Aunty Amara

Good morning ma. Please I want to know what you and my fellow fans think.

My husband’s elder sister will not let us have peace, and the worst is that this woman is married and will not go to her husband's house.

She lives in my house, she does not know how her husband survives,

Should I Apologize Or Ignore my Sister-in-law?

Good afternoon ma, I have been following your post for a long time now.
I need your advice on this.
Am 27yrs old,  married but not officially yet, meaning the marriage requirement list has been fulfilled by my husband but there is no money for the open traditional and white wedding yet to make it official.
