My question involves a child custody case from the State of: GA
my bf has a 3 year old that is biologically his and a 7 year old that isn't. When he met his ex the 7 year old was 6mths old and he took it upon himself to take care of her. He is the only dad she knows. He and his ex broke up about 2 years ago and we have been together for 1 year now. She doesn't want her kids around me or my son and nephew because my 4 year old nephew and their 3 year old daughter were playing under the covers in his room. She was molested as a child and now saying that she is scared for her daughters. This is absurd, although she is a deadbeat with no job, no GED, used to be stripper. He works for the family business and has took care of the 3 year old who has been living with him for the past 2 years. The 7 year old lives with her because technically, she isn't his child. It is hard to maintain a relationship when she doesn't want her kids around me or my son and nephew. We could never get married or move in if he respects her wishes. He has been doing that lately but yet trying to involve me in their life such as outings like bowling, etc. But he hasn't brought them to my house since Halloween. We really think she is more upset that they call me Mommy. She had her kids maybe twice this summer and is not a great mother. She has no education, job, or money and she is probably prostituting to stay in the apartment that she has been in for the past year. What is it that he can do legally? He thinks that he automatically has custody of his 3 year old since she has been living with him for almost 2 years, but I am not sure of that. If he moved into my home she would try to take the baby, and that is what he is scared of even though she has nowhere to run to with the kids because she has no one to depend on in GA but him and his family. Her family in CA don't want anything to do with her. I am in a situation where I don't want to move on, but I don't want to be the cause of her threatening to take his kids. Which she did twice this year, and brought them back after 2 days of realizing she didn't have enough gas to get the little one to school What can he do legally?
