How long have you and this man been dating? How quickly did you ask him to move in with you? My mom always dated and had a string of boyfriends moving in with us...it sucked. If I knew how long you had been dating I could give you advice...such as wait. Wait and keep dating but don't have him move in. Go to family functions together so your family gets to know him and love him like you do. He must have good qualities that they are not seeing. Date for a year. Watch how he is with your son. Does he truly want to bond with your son and enjoy him for who he is? What are his views on discipline? What are his views on parenting techniques? Does he have a temper with your son? Does he ignore him? Honestly...there is no hurry here.
