I don't need any answers from a**holes! I need serious advice from someone who can help me.?

This past Thursday I left my husband because he was being obnoxious and disrespectful. I still can't believe that I actually put him out. My husband got upset with me because I told him that I didn't want to take all of our children with me while I go to pick out a new vehicle. I am the only person in my home who has a job and I don't think its fair, nor do I think it's fair that he wants to send all three children (ages 8, 3, & 11 months) with me while I am trying to handle business and he isn't doing anything except sitting at home, so my husband gets mad and calls me stupid. I didn't get obnoxious back with him I just told him I didn't appreciate him insulting my intelligence. He then proceeded to call me names such as b**ch, , tramp, sl*t, winch over and over again for no particular reason at all so I told him to get all of his belongings and get out. Now he is apologizing and wants to come back home. I honestly just don't feel like dealing with being called out of my name and I feel I deserve better. I try to be the best wife I can but all of my efforts go unnoticed. I need some good sound advice about how to handle the situation.
