Your mother I'm sure is thinking of your welfare. She knows she may leave this earth before you and must be very concerned about you being left all alone, so try to understand her. I'm sure she loves you very much and is not her intentions of hurting you.
Lord help this person find a Christian who they can marry and be happy with and a good provider, so the mother can go in peace when her time to be with you arrives. I pray in Jesus mighty name, amen.
