I'm starting to learn a bit about how you are .. and I notice you need time for things
even though it's for before March maybe you should let yourself give it that much time before you complete that extension application just to be sure
I know he needs you to extend with him but if it's pressuring you then definitely just keep thinking about it
especially since you know how confused you can get.
..just to be safe you think you'll be waiting some more before making your decision
