My mom said she wishes she left me like my dad did?

My parents are divorced and I lived with my mom and step dad growing up. My dad would take my siblings and I every other weekend to stay with him. My dad is a good person but for some reason I truly hated going with him for his weekends, I think I was just attached to my mom and my home and it was really difficult for me to be uprooted from my home every other weekend. I just hated it and would cry and beg my mom not to make me go with him when he came to pick us up, and I would also use my dad’s cell phone to call her crying and begging her to let me come home almost every time. I don’t recall exactly what she would say to me but not once did she pick me up or tell me I didn’t have to go with him for that weekend.

This lasted from when I was a baby (6 months) until high school. We haven’t spoke about it since, but in order to make it make sense in my head I assumed she didn’t let me stay home bc of legal reasons but I always assumed she wished I could be home with her. Well we were in an argument yesterday and it came up that my dad is easier to talk to than my mom because he doesn’t constantly criticize me and tell me I’m immature, etc. (even though I’m 27 with a solid career and relationship). She went off on me and told me she wishes that she could have been the parent who left my siblings and I, and didn’t have to raise us. I told her “I don’t think you really mean that” and she said “Yes, I mean exactly that. I wish I could have chosen to leave and not had to deal with all of the difficulties of raising you kids.” I said again that I don’t think she means to say that and she said she really did mean it again.

Do you think that’s a normal thing for a parent to say to their adult child? Looking back on the conversation I feel like it’s a really cold thing to say and I’m having a hard time getting over it.
