My ex wife and i are divorced because my ex got violent and became an alcoholic shortly after giving birth to my son. And well against my better judgment about a month ago i let my ex take my son and well she put him into the hospital for a week. And i have full custody of my son now. And now that my wife got married back in nov not my son’s mom someone different. Well she is pregnant now and i guess my son isn’t liking that at all he has started to act out horribly and he has never done that before. He and my wife get along great even after what his mom did to him but he is still somewhat skittish i guess the word would be. He will be turning 3 on the 20th of this month and i just don’t know where all this violence is coming from. Advice?
