Why are you financially supporting her? Why doesn't she make any money for herself, at least to help out. Me and my man just broke up after being togehter three years. He was like you he wasn't happy. He cares for me a lot and I love him with all my heart so we are still going to be friends we mean to much to each other to not be a part of each others lives but we or he wasn't happy and the important thing is you both have to be happy. I think that you should have a serious talk to her about what you both want remembering that you need to be happy too. I suspect that a main reason your not happy is because you are responsible for her financially and emotionally. Her mother and her should work things out eventually. All teenagers from 17- 21 have fights with their mothers and feel like they hate them. Some are worse but she should have friends to turn to as well. If you want to leave after your talk or you want a break do it. It will hurt her more the longer you leave it and you will feel guilty. I promise you now that she will cry and she will feel hurt and rejected and promise to change. I think that you could also be helping her gain some independnce too. If you leave remember to still be there for her cause she will need to you but remember be there for her as a friend, Tell her its for the best for both of you and reassure her it will be alright. It comes down to following your heart and if its being pulled in tow directions think of the reasons why
