Okay so my mom's sister has been struggling w/ drugs on and off forever. She has lost custody of her 3 daughters under the age of 4. My mom has decided to step up and wants to foster them. My mom has been in a relationship w/ her gf for almost 8 years literally like 2wks after my oldest was born. So my oldest knows her as gma also and is very close to her. Anywho my mom and her gf are going to seperate cause my moms partner is not up for the task of taking on 3 kids they never even met and etc. Which is understandable. But my mom has made her decision, there breaking up and my moms gf moves out tomorrow she found an apt. very close by, but the dilemma is what do I say to my oldest? My mom doesnt think she can break the news but idk what to say either?
Any advice as how to break the news softly and in a way an 8 y.o can understand? TIA
