As the Bullshit Turns

It's March 08' and I've been in my new apartment a very short time and already my EX is starting her crap. I only want to be away from her but when I think I'm out, she pulls me back in. She has begun to annoy my children but not having any money and them using to much of the utilities. My kids call me constantly and ask me to talk to her about her bitching but I tell them I will but I don't know how much it's going to work. Lately since the divorce she has progressively gotten worse with her unpredicable behavior towards the kids. She knows I go to bed about 9pm each night to get up at 3am to go to work but she called again last night around 11:15 pm to yell at me because my son and her were arguing about him playing a video game and was loud. I told her what does this have to do with me and stopm yelling at me. She paid me no mind and continued yelling at my son as she's yelling at me so I hung up the phone. She called back and yelled at me for hanging up on her and I replied if you don't calm it down I will do it again. She calmed down as I spoke to her regarding my son because he's my son when he does something to piss her off. She said he is always on the computer at all hours and not going to school. I told her to turn the computer off at her specified time and take take the power cord off the computer so he can't go on the computer. She replied then he'll complain about that. I said Angela you are the parent in the house start acting like it. If you give in he's won and you'll never get the control back. You need to stick to your guns if you want to fix this problem and if you don't if your fault and then don't call me because I don't live there so I can't enforce any rules there. This crap would not be happening if I still lived there because sometimes talking and grounding doesn't work but a little old fashion ass whopping is in order if it needs to come to that. I spoke to my son about what has been going on and my son says Yes, he was loud but mom just started to yell at him for it. She didn't ask him to be quiet, if she did he would have done so but she started to yell and he wasn't going to be yelled at by her. My son said he made a mistake and tried to say sorry but she wouldn't listen and the drama was uncalled for. I thought I was the yeller but apparently she takes the top prize. My kids started to call her the bypolar mom because 1 minute she happy and the next a raving maniac. I never thought she would get like this but apparantly she was hiding this side of herself from me. She is a fragment of what I thought she was. I'm so glad that I got away from her but I still fear for my kids. Not that she will do anything to them but just the stress that must be in that house when she blows up, it must be intense. I'm sorry for the kids to have to deal with the bullcrap.
