OK, first take a deep breath and try to let go of some of your fears. You will not be able to make good, effective decisions for yourself and your little boy if you are running scared.
Next, call the National Domestic Hotline for help. Here is the number and website:
They can help you with resources, someone to talk to, good advice, and the type of support you need right now. They help over 16,000 people each month. I have a friend who believes that she is alive today because of their help.
You need to call them this week while he is being kept away from you--the sooner you call, the better. You will immediately feel some relief because you will be getting help, you will have someone on your side, and you will get good information.
Finally, you need to think differently about this man. I believe that you love him, and I'm sure he probably tells you he loves you, but love does NOT include violence. Love does not hurt. You are a worthwhile human being, and you do not deserve to have violence in your life. So whether you love him or not, you need to think about getting away from the violence in order to protect yourself and your child. Your first and most important duty is to your child and to your own safety so you can care for and protect your child. You MUST take this more seriously than loyalty to a grown man who is hurting you and who can take care of himself if you are not there.
This is my best advice, and I hope you will take it. I wish you well, and I will keep you in my prayers.
I want to add that if the court orders your partner to go to anger management and/or domestic violence classes, he can learn to be different and he can learn skills so he will be a better partner. Then you could get back together. But you should tell him that under no circumstances will you be with him until he gets help.
