So I'm pretty much at a point where I have no desire to have a relationship with ss4. NONE. I don't like him, and I hate having him at my house. His behavior and the way he speaks to people has been unacceptable to me for a while now. When DH and I first began dating I made the mistake of trying to be super stepmom and do everything for ss4. Needless, to say I got wise and realized that my effort was pointless and now I don't do anything for him unless it's absolutely mandatory. 

Recently ss4's behavior has improved a little bit (not as much as DH gives him credit for, but there has been an improvement). DH said to me "I hope that as he changes and improves, you'll be more involved with him." My question is: Is it possible to go back to that? Can I go back to the place where I liked ss4 and wanted to do things for him? So much has happened over the past few years and I just can't imagine having a relationship with that kid, nor do I want to. I don't like him at all and at this point I don't have the desire to have a relationship with him, even with the improvements in his behavior. I just feel like that ship has sailed...
