Final straw..

I called CAS on my kids father yesterday. We have 3 kids together, ages 13, 10 and 7 and my 13yr old lives with him 3+hrs away..well my son called me yesterday crying hysterically saying that dad and his gf were fighting again and he was scared and wanted to come home. This isn't the first time this has happened, he went to live with him in april and this is the 3rd time he's asked to come home now. But every time I get ready to come get him, he changes his mind-but its his father feeding his head full of chit. His dad and his gf fight constantly, keep in mind this is the chick he cheated on me with the last 3 yrs of our 12yr relationship. She accuses him of everything, she gets physical with him and as of yesterday he hit her back after she hit him. So he's still abusive and hasn't changed a bit.

Well I'm tired of my kid being there in the middle of all their crap. His gf can't stand the fact that he has kids from before her, shes 10 yrs younger than he is and immature as ever. I have had to drive up there days and even weeks early to get my kids because she freaks out when he spends time with them and she kicks them all out of the house. i got there on boxing day to find my kids sitting outside in the parking lot with all their luggage in the cold, it took me 4hrs to get up there...I could've killed her. My son knows that she hates him, she yells at him and shes abusive to his father right in front of him. I packed up my kids and left him almost 3 yrs ago because our relationship was just as bad. and now my son is re-living it all over again. He can't go to counselling because hes afraid to say what really goes on at home. This is the 5th time in about 6 months that the police have been called out to their house because of this domestic crap. I called CAS yesterday as well as the police out there to get a car over to the house but they had already been dispatched. I had an officer and CAS worker call me back after they had done a check and neither their dad or his gf would say what happened so nobody was arrested and no charges were laid. The kids were deemed safe in the house. I am never in favor of having anyones kids taken from them but in all honesty I left this situation before because CAS threatened to take my kids if I stayed in a situation like that...so what gives??

I want my son back home, he is stuck between staying with his dad because he keeps telling him they will get their own place without his gf but never follows through..and then he wants to come home to me and his brother and sister because he misses us and he feels safer here. I will fight to get him back home but I also don't want it to be tramatic for my son, all my kids have been through enough. I feel so stupid for letting him go live with his dad

I just pray that this can be solved sooner than later...I'm so stressed out from it and its affecting my pregnancy. Any encouraging words would be great...thanks for reading..I just feel at a loss as a mother, like I've let my son down
