mil ruined a part of my wedding

Hi everyone we had our beautiful wedding in March but I have some anger towards my mother in law still... so as a back story she never goes to any party she always says she does not like parties etc etc so when we first got engaged she would say that she will not attend our wedding and would rather die than come to our wedding... than she said if there was liquor she would not attend (does not drink - neither do I but her son and our friends do) than it was will come but not dance with her son or walk in to party or ceremony. Fast forward a week before the wedding I told her we would have a car pick up her and father in law at 3-3:30 in the afternoon so they can leave Queens to our venue because it was a Friday afternoon we know what the traffic can be like, she said no that it was too early I said no you need to have enough time for traffic.... well she ended up leaving her home at 4:30 because all of a sudden the week of the wedding husband's cousin who happens to be mil favorite person ever decided to come to the wedding (hello change of seating chart!!!!) so since she flew IN THE MORNING OF THE WEDDING her and mil complained that husband or his siblings who were at the hotel getting ready could not go get her... she took a cab to mother in law's house and decided to sleep all day... my mil felt bad to wake her up so instead showed up an hour late for family photos, we did our plan B my family photos, quick walk through and than were just sitting around waiting for them!! now I am devastated like you really couldn't be on time, now this I could have gotten past.. but as she shows up an hour late when the photographer is trying to take the pics she is pretending to be asleep, looking down, turning her face, closing her eyes insisting she does not want to take any photos!! I started shaking I could not breathe I was literally about to faint!!! so here is the kicker, we had the list of who to take pics with his cousin decided last minute to come she was not on the list so when we took pics with the last group of his family we called her to take a pic... mil comes on her own and says "me too" and I simply said no... hold on so you're telling me you couldn't take 1.pic with your son 2.pic with your kids and husband 3.pic of whole family but you now want a pic with your niece!!! I was livid... this just ruined my day I know something so small but to this day it still bothers me... than at the party she was dancing on chairs!!! but was making all of this fuss. She also declined to my bridal shower but ended up coming at the end with my husband, she declined because she was too shy yet walked in like Mrs. America so loud and when we were playing games was shouting out commentary ! the day prior to our wedding we went to get the marriage license and she said she lost husband's birth certificate, we went to the office to obtain the license and you know they would not give the license without the birth certificate even though he had everything but it and I understand that I do... but than tell me how all of a sudden she found it so we had to go to her house get it than go back to the office... delaying his hair cut, my nails, our day etc etc... I just feel like she has been a monster. please do not judge me for saying this, maybe getting it off of my chest will make me feel better, but whenever I think of my wedding I cry or get upset or a headache all I can think of is her!
