CA marriages that last under 10 years are considered "short term," but the date of separation in this case may be arguable, and anyway, the dates only create a presumption that can be rebutted by proof of the parties' intent and continued work on the relationship, marital activities together, etc.
When determining spousal support, the rule of thumb is that support will last for 1/2 the length of the marriage, but there are so many other factors involved, that's just a guideline, and there are likely arguments to increase or decrease it.
You shuld see a family lawyer to disclose everything about your and your spouse's current and potential income, assets, liabilities, etc., to get some specific advice.

It sounds as if you are headed for a court battle over date of separation, as you are both aware that a 10-year marriage is generally considered "long term" -- which can significantly affect spousal support.
Date of separation is set at the time the parties are unambiguously living "separate and apart”. That is the date at which spouses are physically separated due to a COMPLETE AND FINAL BREAK in the marital relationship, with NO PRESENT INTENTION of resuming the marital relationship.
Simply “living separately” is not sufficient. At least one party must INTEND to end the marriage. But is it not enough that one party simply asserts that was his/her intent. If there was no unambiguous written or witnessed statement of intent, THE PARTIES' ACTIONS must “bespeak the finality of the marital relationship”. And that doesn't just mean now and then; the actions must evidence the CONTINUING intent from the alleged date of separation on. So, although intent must be proved, the proof of intent is in acts.
Arguably, spouses can be “living separate and apart” even though living under the same roof, but there has to be “unambiguous, objectively ascertainable conduct amounting to a physical separation under the same roof.” And, arguably, even though spouses are living separately, they may still behave as if married.
It will come down to who can present the best evidence -- and as always in court battles, documents and witnesses are essential. The court's standard for deciding between the competing claims is "preponderance of the evidence" -- basically, which set of evidence the judge finds slightly more convincing than the other (think of it as 51% more likely than the other set).
You would be wise to consult competent counsel on this one.

This is a factual dispute, the result of which will have a substantial effect on the awarding of spousal support and division of property. Any facts that show an intent to return to the marriage such as attempts at reconciliation would help to strengthen your position
It is strongly advised to seek the advise of counsel in this matter.
