Actually I understand only too well. I know the OP's situation is no good because your partner should be supporting your dreams/goals/aspirations and vice-versa. You should never have to ask permission, or convince someone to "let" you pursue your dreams. Nobody who truly cares about you would ever try to stand in the way of it.
"Because I really want to" is reason enough for anyone you're that close to. Bringing in a bunch of unknown people on the 'net to help you plead your case is a defacto admission of a lack of closeness/belief/trust.
The act of convincing is an important one. You need to convince your spouse that it's important to you. More important than all the other concerns (that's the hard part).
