Rant-I’m sorry😬

My mother whom didn’t even raise me, calls MY baby her baby. Example: “We’re about to see our baby, well I know your baby but he’s mine too I birthed you”.(Actual text she sent me). I have been trying to forgive her for basically abandoning her children for drugs and men and letting her be apart of my life and my pregnancy. It’s been hard to do as I don’t feel she deserves it nor do I remotely trust her to ever be alone with my child. So her calling my baby, OUR baby or HER baby really pisses me off to no end. I don’t feel she has a right considering my grandmother raised me. She’s more of a friend that I tolerate in small doses rather than a mom and I hate that but it doesn’t change the feelings I have. Also, I have told her not to call him her baby that he is mine. I have also told her how easy it is for me to remove her from our lives if need be. Am I being a complete bitch about this or am I a little valid? Sorry for the long post🙃
