My son Jared is 5. His father and I have been devorced for about 3 years. I am in a healthy relationship with my boyfriend for 2 yrs, who gets along well with my son. My son has never had a problem with my bofriend. My ex husband just got married to a woman he was dating for about 6 months, three weeks ago. She has a 11 yr old daughter who also gets along great with my son. For the past three years he had delt with the divorce very well. To the point where his kindergarden teacher was even impressed. His father and I rotate weeks to have him ( I have him one week, he has him the next week). I just got him back from his dads' and everything seems normal until the next morning. I took him to school and when I tried to leave, he began to cry uncontrolably and very hard. I sat him down and asked him why he was crying. He said that he didn't want me to leave him. It took me close to an hour to get him to calm down and go into class. When I picked him up from school, his teacher was concerned. She told me that today was very hard for him. Throughout the day, he had crying spells and when she was able to get him to calm down he told her that he just wanted his mom. What is he really going through? What do I do? Please help me.
