True Story : My mother asked me to bring my boyfriend ’s $perm if I want him

I’m a 36-year-old single lady. I have been dating this
guy for over 4 years and he promised to marry me.
On several occasions, I have caught him cheating on
me. Once I caught him in the act, he begged me and
I forgave him.
After one year, I caught him cheating again and I
told my mother. She advised me to bring his sperm
to her and she would make him marry me in less
than 4 months.
I am confused.
I don’t suspect she is a witch or anything like that
because she is a prayer warrior in my church, she
sees visions for people and they come to pass.
My question is, what does she want to do with the
sperm?
I have asked her several times and she says I should
not ‘question the spirit’.
I am also scared because I don’t want him to
abandon me after so many years of dating and go to
marry another woman. I have suffered with him.
Do I tell my boyfriend what my mother asked for?
Or do I just do as she has said? I know she is my
mother and will not mislead me.

Please, I need your advice.
