HELP A BRETHREN

PASTOR, I HAVE FOLLOWED YOUR TEACHINGS FOR A WHILE NOW. THE LADY I WANT TO MARRY HAS A MENTALLY UNSTABLE BROTHER & SISTER AS ELDER & YOUNGER SIBLING. HER MUM ALSO LOOKS NOT ‘QUITE RIGHT’. MY MUM THINKS INSANITY RUNS IN HER FAMILY & I SHOULD KEEP OFF. I HAVE ASKED HER BUT HER RESPONSES HAVE BEEN NEITHER HERE NOR THERE. I LOVE HER; AT THE SAME TIME I DON’T WANT MY KIDS EXHIBITING THOSE TRAITS IN THE FUTURE; HENCE THE NEED TO BE SPIRITUALLY GUIDED ARIGHT. SIR, CAN I PROCEED OR SHOULD I CALL THE RELATIONSHIP OFF?
