hmmm 11 years is a long time. Take the time to be true to yourself and ask yourself.. Do you love him or the fantasy of being with him. You are so young & while time is not on your side, it seems such a risky situation. I think I would ask for more commitment fro him. He needs to pull his weight & realise if its you he wants to be with then its not fair to string you along till next year when you have so much riding on things with your medical condition.
