How can people not love their children?

Rant about how insane is it to me that my own mother didn't bother to respond to my texts or calls all of Christmas weekend, despite the fact this it was my daughter's first Christmas. I'm one of 5 children. My mom has no contact with my little brother and is now acting like I don't exist. As a new mom to an amazing almost 5 month old little girl, I can't understand how a mother can just drop her children and ignore them with no reason given. We normally talk daily, but Friday she didn't want to take because Little House on the Prarie reruns were on. Since then, she hasn't returned a single call or text. I have no idea what I could've done, but this isn't the first time this has happened, and I don't know how much longer I can try and fight to have a relationship from her. It seems that unless I'm offering money to her she doesn't want anything to do with me, and I just can't take it anymore. I've been struggling with this for years, and since she's got cancer I've been trying while she's still around. But when does it become acceptable to end the toxic relationship?
