My grandma left my grandpa last year and ever since she left him she hasn't bothered with me or any of her other grandchildren or family. The only person she has been worried about and had anything to do with is my aunt and uncle that live an hour away. She moved to where they are to be with them. She never even talked to me the whole time I was pregnant, and she never even asked about Tinley. I had made the choice to not even bother or try to get her to talk to me because I refuse to beg anyone to be a part of mine and Tinleys life. I shouldn't have to in the first place. Well anyways she caused a lot of problems with my mom to where she was literally driving my mom crazy. We had to get all of our numbers changed and everything. Well like I said we haven't spoke for over a year, while I was in the hospital after I gave birth to Tinley she showed up to the hospital, but I didn't know. I had it set to where no one could get through the doors to labor and delivery unless they had a four digit code. Well when she came to the hospital she stood at the doors and waited until someone came through them then she darted through them and was trying to figure out what room I was in. The nurses had to make her leave. Well we didn't know until they came back and told us. She then messaged my mom blaming her and going off on her. So I messaged her and told her it was my choice to have it set like that and of course I haven't heard from her since. She has never even asked about Tinley since she has been born. Well she messaged my mom today going off on her again for God only knows what and then messaged me out of the blue asking me if I was happy to not have her in my life anymore. Like wtf. This woman is literally crazy and needs help!
