Update: So after many weeks or procrastination and dropping hints her son is not happy with me, I bit the bullet and gave them their notice today.. In my contract I say I will give two weeks notice. In this instance I gave her almost 3 and she is all peed off. She then asked if I would take him for drop ins! Umm no! I'm so relieved to have finally told her but feel like I could use a drink lol (hardly ever drink). Thanks to everyone for ur advice!
