well my 3yo sons father is very inconsiderate and incompassionate, and I feel like he uses me all the time. I went back to nursing school after getting layed off about 8 months ago. I was having a very hard time finding a job so I decided to go back to school. well he has been a part of my support system for the time being. he works mornings 12 hour shifts ( if that) he lives about and hour and half from me so if he keeps my son while im at school or work he will take him to his place. now im in school 6 hours out the day, externship/ clinicals for 8 hours and somtimes work study 3 hours every other day... so you know I'm pretty tired after. well besides the fact he always wants me to drive that whole hour and half after my long days to come and get our son from his place, then drive all the way back home EVERYDAY (3hours total).. I ask him if he could meet me half way at least because im super tired. he always complains and says well I work all day and I'm tired, then he will say I have to work in the morning so you will have to come and get him. needless to say if he called me up and he wanted to get our son I wouldn't hesitate to meet him half way because I know its a long drive and I know he could be tired. we have a court order for him to get our son every other weekend but he never gets him. he always want me to bring him over on the weekends (fri-sun) I take him because I want him to spend time with his dad, and I will do anything to make it happen. the problem is he expects me to do everything, concerning our son plus more like cleaning his house and cooking.. (not that I dont want to, he's my son too lol) but its not fair. when I'm there he wants to have sex too. I just feel as though if we aren't together there is no need for me to keep coming over and "play house" if he won't committ. I just dont know how to walk away. he threatens to take our son from me if I dont come over or if things dont go his way he's mad rude to me. advice please?
