Over it

So i have a "friend" i go to 99% of her kids parties and things ill go uo to her house to visit every now and again but every time and i mean EVERY time i invite her to something she says yes shes coming and then doesnt show up i invite her to bday parties doesnt come i invited her to my gender reveal for my son didnt show up i invited her to my babyshower didnt show then she messages me on fb and says she has stuff she wants to give me for my son who is due in jan she says she will come down thursday so i message her tonight wednesday and ask if she is still coming....no responce but she saw the message shes posting on fb and all im so over it i know at this point she wont ever show up to anything and im really annoyed dont try to make plans and not show up every single time. Id rather you tell me hey sorry i cant make it or say hey im gonna try to come but idk if i will make it dont tell me yes and not show up dont message me saying you wanna come down if you cant respond when i ask if your still coming. Its so rude and disrespectful its a waste of my time and im done ive known for awhile if you say yes not to expect you to really show and thats just sad.
