Advice on people leaving my kids lives.

My best friend and I had a falling out. She has been in my kids (6M and 3F) lives since my son was about 18 months old. We knew each other longer than that but she missed a chunk of his baby years because of Covid. We went to high school together and have been friends for about 13 years so when I had my kids she was their aunt no question.

Very recently she has been going through some mental health issues and taking care of a dying family member and things between us started becoming tense. Long story short things happened and she told me she no longer wants to be in my life.

My kids consider her family. She was family. I don’t know how to talk to them about not seeing her anymore. My son asks me to send her pictures of them and videos. My daughter does figure skating and will ask me to send videos because it’s something they both loved. I understand that she was going through stuff and I really don’t hold it against her but how do I talk to my kids about it without them feeling abandoned or unloved?

Some of the things she said about them made me really upset at the time. Basically that she’s tired of being my support system and she misses who I was before kids. It felt like a slap in the face to the kids who love her but I didn’t have it in me to argue about it. So now I’m trying to process and figure out what to say to my kids.
