What is the name of your state? ga

I filed for divorce in two and half months ago after my husband slapped our 1 year old in the face and pushed him face first into the floor. The police did not arrest him because there was no physical evidence (marks on the child), and though he had admitted it to the lady we were with at the time, she did not see it happen, only I did, and he denied it to the police. DFACS became involved and did not let him see our child for over a month and now can see him, but only supervised visitaiton. It was not the first time with the child, and I had went around with bruises on me for almost 2 years (hidden ones, never in the face). He signed himself up for anger management after he was told by DFACS that "abuse and/or neglect" was proven correct. He extended our court date an extra 3 months because he wants custody**************..here's the twist. He is trying to prove me unfit. He says that he has witnesses that will testify to me verbally abusing him (even though I have three witnesses to him either slapping the child or slinging me around, and more than that who can testify to verbal abuse from him to me), he also says that I drink and he doesn't (which he has, but not as often as I do), and that he was the main caregiver for the child. Also, about one month after I filed for divorce, a male friend and I began a relationship. It was more emotional at first, but now we have had physical contact, not sexual intercourse though. I have been cautious, but not as cautious as I should have been. Most of the time we are together we are with a group of people, but not always. Only one person has seen us kiss, and no one has seen anything else. I just found out that he extended the court date, so I have now stopped the relationship to be on the safe side, and we are only going to see each other in a group of people (which again, we dont even hold hands around any one, and they all just think there MIGHT be something there, but as far as they KNOW, we are just friends like with every one else). If he has hired some one to follow me and has caught on and can prove adultery, can I lose custody?
