AITA for refusing to babysit my grandkids because I don’t want to

I am in my late 50s, female, married my high school sweetheart. We have 2 children, son, 17, and daughter 16, These are fake names fake ages but I want to protect my family here since there are some details I’m going to share. Our son, Cameron and our daughter, Taylor. We live in Pennsylvania, Cameron lives in California, and Taylor lives in Arkansas. Our children are adult and no longer live with us. <br><br>I am the family caretaker. Not everyone is happy with this situation. I love to help my family, I really do. But for once I wanted to say no. <br><br>I just adore my grandkids, 13M, 10F and 3M. And I love spending time with them. I baby sit them whenever I can, take them to appointments, pick them up from school, buy them gifts, I could go on. My daughter Taylor is their primary caretaker, but since she also has two other kids with her husband, she gets overwhelmed. Which is why most of the babysitting is done by me. <br><br>My husband is a well off man, and has from day one told me to never say no to our family. Which I don’t I have a problem with until recently, when I wanted to put myself first. I am divorced, no boyfriend, kids grown, and finally at an age where I could start focusing on me. <br><br>My daughter informed me she also was pregnant, due in November, and that her husband wasn’t working so I’d have to baby sit all 5 kids. This was unacceptable to me. I refuse to help, I told her my husband and I are planning a trip. This upset her and my son, Cameron sent me a text saying I’m being selfish and cruel. My husband got me a bouquet of roses and told me to help my family, I refused and told him this was one time I put myself first, and if he didn’t supported me, I’d divorce him. <br><br>I know I’m not a bad person. I love my kids, grandkids, and I want to help, but I don’t want to just do this. I want to want to help. <br><br>AITA?
