Friends...

So I have this friend I've known for 17 years.. Over the last 6 years it's been rocky because this person has lied to me on several occasions flaked more than I can count.. And has an excuse for everything... She missed my wedding last year her excuse the next day was she had woke up sick but that night I see pics of her and someone at great America... She then moves out of state without a goodbye or anything new I have to find out from her mom/Facebook... When she returns she invites us to her daughter's birthday last min but we show where her kid bites my 11month old for no reason drawing blood and she was like o well... If me and other peopl invite her out she says she can't go cuz her mom won't baby sit or she is sick... On her birthday she invites me out but then ignores me via text about where to meet.. She  went to great America with her friend from outta state... On my birthday she didn't go cuz she was babysitting her friends baby at 6pm who is a week old so the mom can do laundry... Movie was at 945.... Then for my sons birthday party she said she would come but yet ignored my texts.. She read my message on fb ... She writes me today saying she wasn't ignoring she was just dealing with life as her dad got into a motorcycle accident in Modesto... However my dad who is close to her grandfather informed me that her dad isn't allowed to drive any motor vehicle due to a brain injury and he don't know where Modesto is.. I'm like really and they were like ya she just didn't want to go .. I said that's shitty to use her dad as an excuse..I called every hospital in Modesto before this so I can pay my condolences because she said he broke his left shoulder and broke a small bone in his right shoulder and having surgery on his arm.. Common courtesy is to say something not ignore me all day... And then text me next day like its nothing...
