What Does My Ex Expect Of Me Now After Divorce?

Well, to be honest, my ex better not expect anything of me anymore. I was married to him and wanted it to last for the rest of our lives, but it didn't happen that way, so now, he's on his own. My ex spouse has asked things of me since I left, though. He wanted my help on fixing his taxes...yes, that's right. He trusted me on helping him. He also asked my help with my allowing my name to stay on the electric and phone bills, which I did with a time limit to allow him enough time to get them into his own name. What does my ex expect of me next? What ever comes next, he's on his own and I am done with all those little things that he needs to have done. He's with the other woman now so she can get those things done for him. I am not going to allow him to demand anything of me anymore, those days are over. I don't have to answer any of his calls, unless it's to talk to his daughter, but honestly, since she's a teen, he can call her on her own phone. He has decided that he doesn't want to know about her grades in school, or make any decisions that he's entitled to. What can my ex get from me now? How about a well behaved ex wife who doesn't scratch his eyes out for cheating?
