Kathyanita,

If you want to quit the job and not hurt her feelings maybe it is best if you can explain to her that it is time to movw on for you. Time for a new opportunity.

"Children" move from under the "mothers" wing every day. Good parents know this is natural and healthy.

Otherwise there may be no other way than to just move on. It may cause her pain but above all you must protect yourself while causing the least amount of harm to others.

Take care
