I strongly dislike my MIL right now. She is ruining my birthday all because i was going to take my daughter wih me to my moms for a night and then be back the next day to go ot to dinner with everybody after a day of shopping for the new baby. She is acting like a child and now I am to the point of not even goig out for my birthday dinner and just stayi g home and laying in my crying wih the door locked. What a way to spend my 23rd birthday. I told my mom tonight that if my baby boy decides to come on my birthday that it will just be her and my SO allowed to be at the hospital with me. And personally im going to tell my SO that I do not want them to visit us until I am ready and she is ready to apologize for the way she is acting.
