Thank you for bringing your question to Just Answer!
I'm afraid that in your eagerness to support his work, you overstepped some boundaries of a new relationship. You made life changes (occupation), drove 11 hours to see him when it wasn't necessary, and you've taken charge of his career.
For a man with a long history of bad relationships, this would be overwhelming. While as a wife it may be appropriate to do so much for a husband, it could be seen as too much for such a young relationship. He said not to come when he was sick, but you decided you knew better--putting you in more of a mother role than a girl friend.
By doing too much, you removed any sense that he needs to work to earn your affection. In general, men need to feel that they need to step up to win a woman's affection. By too quickly devoting so much time and energy to his needs, you took away all sense of the quest to win you.
Also by doing so much, even though your intent is to help and get his music out into the world, it makes him seem like he's not competent to run his own career and get himself recorded. Men need to feel strong and in control of their lives. Too much help can take that feeling away from them.
Perhaps if you backed off a bit, were not quite so available and focused on him, it would re-spark his interest. It sounds as if you two have a lot in common, but in the excitement of meeting him and discovering what a great musician he is, you got too involved too fast and overwhelmed him.
If this doesn't re-spark his interest, and you eventually start dating someone else, I have two books to recommend:
The first is Temptations of the Single Girl Thisbook should be required reading for all women before they start to date. The"temptations" are thinking that we can change a man or his behavior, committing to him before he commits to us, settling for a man who doesn't want a commitment and wasting time with the wrong man because we're afraid to be alone.The other is Why Men Love Bitches: From Doormat to Dream girl. http://www.amazon.com/Why-Men-Love-Bitches-Relationship/dp/1580627560/ref=sr_1_1?s=books&ie=UTF8&qid=1323176433&sr=1-1 There are over 500 positive reviews of this book, so don't write it off because of its title.
