I recently got married to a woman that had two kids. I a man that was raised to take care of responsibility so it came natural to me to care and love for the kids. At first all was going well and dandy. But lately the 3 yr old has been acting weird. Every time I come around him he cries. And whenever I hug and kiss his mother he runs and gets in between us. How do I let him know that I am not here to take his mommy away from him, and how do I get him to stop crying whenever I come around him?
