Amor'e,
I agree with everyone who has offered you their sage advice. You need to get away from the abusive relationship and I think it is best to move back to your Mum and take a little time to find yourself. Living back with your Mum will give you the backing you will need when looking at custody issues and the ability to care for your child.
I have been helping my sister in-law over the last 2 years with guidance during her separation and now divorce. Through the whole procedure her ex husband has been extremely difficult and has lied consistently and has tried to sway their 4 children's view of their mother. What I have witnessed is that children are very aware and are not blinded to who people are. They have 4 children 2 girls and 2 boys from age 9 to 16, they all do not want anything at all to do with him and this has been from their view and have not been persuaded in any way.
If you stay calm in all of the confrontational situations, never say a bad word about your wife and always have your child's best interests at heart you will never lose them. Some days will be harder than others but the end result will be worth the pain.
Please stay strong and be who you want to be. Your child will see you for who you truly are whatever the form you wish to take. The old saying of "True beauty is the beauty from within" is how children view the world so be the beautiful person you want to be. You are also very lucky to be beautiful on the outside as well.
I wish you all the best.
