Will i continue to teach a woman friend to drive that now his husband is getting jjealous of me?

I would like to help her assist her husband in dropping and picking up their son at school and extracurriluar activities since her husband is night shift worker. She is a slow learner as some do in their later years so we are spending more time on the road and maybe this is the reason. I do not know. Please help me as much as I would want to help them.
