Joshua Malina’s Wife Melissa Merwin Files for Divorce

Joshua Malina‘s love story with wife Melissa Merwin has come to an end … as the mother of his children has filed for divorce, TMZ has learned.

In new court documents obtained by TMZ … Melissa filed to end her nearly 28-year marriage to “The West Wing” star, who she married back in December 1996. The docs are from Melissa’s side … so, this is her perspective on the whole breakup.

In the docs, Melissa cited “irreconcilable differences” as the reason for her split from the actor … though she did not list a date of separation.

She is seeking for JM to pony up some spousal support … but she isn’t looking for child support or a custody agreement, as their 2 children are already grown.

Melissa’s filing is pretty cut and dry for the most part … and it appears she is seeking to amicably resolve this divorce with Joshua … with minimal court intervention.

Joshua and Melissa’s romance dates back to 1992, when the actor first met the costume designer via Melissa’s sister Jennifer and former brother-in-law Timothy Busfield.

Joshua — who is best known for his work on “Scandal,” “Sports Night,” and “The Big Bang Theory” — has kept his marriage out of the spotlight for most of his career … with Melissa rarely making an appearance on his social media accounts.
