Is it forbidden to keep away from a maternal aunt who has caused multiple problems, including the dissolution of four engagements, and without any success in advising her?

An maternal aunt is in the position of a mother, and it is obligatory to maintain ties with her and forbidden to sever them. Part of maintaining ties is to advise her and correct her shortcomings. If she persists in evil, then there is no harm in avoiding her to guard against her mischief. However, it is not permissible to sever ties with her completely. Rather, it is obligatory to maintain ties with her in any possible way to secure yourself from her harm, such as calling her and inquiring about her.
