Jane Lynch -- My Gay Marriage Is Over

Jane Lynch is pulling the plug on her marriage to wife Dr. Lara Embry ... just 3 years after tying the knot in Massachusetts, where gay marriage is legal.

Lynch just released a statement to People.com saying, "Lara and I have decided to end our marriage. This has been a difficult decision for us as we care very deeply about one another."

The 52-year-old "Glee" star met 44-year-old Embry back in 2009 at a fundraiser in San Francisco ... and they married in 2010.

Lynch and Embry are California residents and a California court will almost certainly dissolve the marriage, even though gay marriages are not legal in California. The State recognizes marriages from places where gay marriage is legal.

Now ... California is a community property state, which means unless there's a prenup, Lynch and Embry would split all assets acquired during the marriage 50/50. Although Embry's no slouch, Lynch has made a bundle on "Glee" and other projects.

Sources connected with the former couple tell TMZ ... they don't have a prenup.
