My spouse and I are starting our divorce and we don't talk to each other, I don't know whether she is going to itemize deductions or not. What do I do?

Since your spouse needs the same information from you, ask your divorce attorney to obtain it.  (And if you live in a community property state then you might need to allocate income).

If you take the standard deduction, and she takes the itemized deduction you won't qualify so your deduction would be $0.

Best thing is to text her or something to find out.  If you itemize and she doesn't, she would also have $0 deduction. 

If she is likely to itemize, then you can itemize. 

"You and your spouse can use the method that gives you the lower total tax, even though one of you may pay more tax than you would have paid by using the other method. You both must use the same method of claiming deductions. If one itemizes deductions, the other should itemize because he or she won't qualify for the standard deduction"https://www.irs.gov/publications/p501#en_US_2018_publink1000221053

If she absolutely won’t communicate with you choose the deduction that is better for you and if there is a conflict the IRS will send you a letter to sort it out.
