Another one of Eliza Coupe's husbands wants out -- 'cause he just filed for divorce ... TMZ has learned.
Eliza's hubby of almost 4 years, Darin Olien, filed legal docs Monday seeking to end their marriage. He lists the date of separation as March 27, 2018.
It's unclear for now if he's seeking spousal support -- the couple had no children together.
Darin and Eliza got married in December 2014 right on the heels of her first divorce from Randall Whittinghill -- whom she had to pay $7,000/month in spousal support for 2 years.
She also had to shell out a lump sum of $306,000 at the time. Only time will tell if this ending will be any happier ... money-wise, we mean.
