GRRRRRRRRRRRRRRRRRRRR!!!!

I'm getting EXTREMELY frustrated with a certain someone named Pete. He needs to grow up and stop making me and my daughter in after thought. He REALLY needs to stop making promises to my son. You can't tell a 2 year old something and then not follow through... he doesn't understand and then MOMMY has to fix it. EXAMPLE: today he called and said he had to come up to Columbus for something so he was going to come by and see us before he had to get his mom from work.Great.... I had a long night with Kenley and having Aiden out of my hair for a little bit was VERY needed. Well I ran into town to visit my mom until he got here. Well as soon as I pull into Marsh, Pete calls again. He said his mom got off work early, but if I wanted to bring the kids down to his house so Aiden could go swimming I could. Still great... still got a little time to relax with Aiden occupied. Then he texts me and says he is going to his family's house for dinner. This is where I got mad. I had to tell my son he couldn't go swimming and of course he burst into tears and I looked like the bad guy... AGAIN!!! I'm so over it. It's time to realize you now have a child and you NEED TO HELP ME take care of her. I understand I am breastfeeding so I HAVE to get up with her to feed her, BUT when she's not eating I could use some relaxing. He just doesn't get it. He thinks coming around when he feels like it is help and it's really not. I'm so over it. I want to just throw in the towel and tell him to leave us alone, but I know he'll end up making me feel like a huge bitch and I'll go back on it. UGHHHHHHHHHHHH!!!! AND OF COURSE... as I type this Kenley is really fussy and I just want to cry!!! FML!!!
