My girlfriends son has been crying lately for no reason at all if you even look at him wrong he just bursts out crying. I've been reading online that it could be a sign of abuse but when he's home I'm around him almost the whole time and I know his mother wouldn't be doing anything like that. He goes to his dads every now and then and when he comes back he acts totally different hes obnoxious and won't listen to anything you tell him and he will hide from me when his mom first brings him home like he's scared of me until I give him a toy or pick him up and start kissing and hugging on him then he seems to be fine with me but still cries about rediculious things that make no sense to cry about. I don't think his father would be abusing him either I know he has basically no rules when he goes over there and his dad goes out and parties pretty much every night hes there and his grandpa always watches him. Sense i'm pretty sure he isn't being abused do you thing his father is telling him that i'm bad and filling his head up with stuff? For a long time his father didn't know that I was with his mom and seeing his son all the time and he used to love me and be mad when I left and follow me around and even call me Daddy when I didn't teach him to. Now he doesn't do any of that and calls me Mike. This all started after his dad found out that he was hanging around me. I'm also worried this could be some sort of Autism sign. He is 3 and a half years old now do you think this is some kind of disorder or that his father is filling his head with stuff? What can I do about it if he is to make him love me again?
