@LH2011 - Just complete your tax return based on what is best for you.
If you itemize, the other spouse will be forced by the IRS to itemize (but not your issue as the IRS will inform the other spouse).
If you take the standard deduction, the IRS will let you know if the other spouse itemized and adjust your return accordingly.
if you both take the standard, then all is good. if both itemize, then all is good.
the other spouse has no requirement to tell you anything about their return, or even if they filed one.
RS Publication 501

Also note, if you don't know your spouse's social security number, then you have to paper file; efile is not available. IRS rule.
