The Ungrateful

So here I am sitting and waiting. Worried and angry. Let me start from the beginning. A few weeks ago, right around the time my dad got sick, a friend of mine showed up on my doorstep unexpectedly. I just came home and there he was, homeless once again and needing somewhere to stay. Well, it just so happened I was in desperate need of some help. I needed help keeping up with the house and someone to take dad for treatment in case of bad weather or me being to sick to drive. So I struck a deal with him. You can stay with me if you work for me. Now I must note here that the guy has never held a job longer than a few months and jumps from one bad long term relationship to another. And so he agreed. It didnt take long for me to realize that he has a true addiction to the internet. And it also didnt take long to realize what he was doing on there. Now I also have to state that there were rules set up as part of the deal. He would be home on the nights where my husband had to work the next day so that I didnt have to drag all the kids out to take him to work. He would be home no later than 10pm and if he wasnt comming home he would call before that time and let me know. I am a worry wart. I think of all the worste possible things that could go wrong. He walks everywhere. So I am terrified that he is gonna get run over and I am never gonna know what happened. Hes gonna lie bleeding to death in a ditch somewhere. You get the picture. Well Wednesday he decided he was going to meet this chic he had just met online and spent the week end with her. Its not the first time this has happened since hes been staying here. But he said he would be back by thursday night. Well thursday evening he called to let me know it was raining and he would not be back. I have not heard from him since. I have always been there for him. Always stuck by him even when his family deserted him. He knows how much I worry and at the moment how much I depend on his help. For 8 weeks now I have made sure he had food, a roof over his head, clean clothes and provided internet use. Now he has just went off with some slut hes met online that will soon tire of the fact that he is truely a bum and Ill be left to decided if I want to let him come back or severe ties for good. He only cares about himself. Its always been that way. Hes selfish and self centered. He has no manners and no sense of duty. But I love him. Ive known him my whole life. He is litterally like a brother to me. But Im angry and hurt and really want to hurt him. So what do I do when he finally shows? Opinions anyone?
