The head of South Carolina’s statewide LGBT advocacy group will marry his partner of nearly five years at Baltimore City Hall shortly after midnight on Jan. 1.

“It has been a long-time coming for us as a couple,” Ryan Wilson, executive director of South Carolina Equality, told the Washington Blade on Thursday. “Having the legal recognition for us as a couple is really important to us.”

Wilson, who grew up in Fallston in Harford County, met Shehan Welihindha in Detroit in 2008 during the National Gay and Lesbian Task Force’s annual Creating Change conference.

Welihindha, who is from Sri Lanka, is studying for a Ph.D. in public health at the University of South Carolina. He is the part-time coordinator for the Harriet Hancock LGBT Center’s program that seeks to prevent HIV among young gay and bisexual men in Columbia, S.C., and the surrounding area.

Wilson proposed to Welihindha in 2009 on-stage during the annual South Carolina Pride as former “American Idol” contestant Frenchie Davis and thousands of others watched.

South Carolina will not recognize the couple’s Maryland marriage because voters in 2006 approved a constitutional amendment that bans nuptials between same-sex couples. The Defense of Marriage Act also prohibits Wilson from sponsoring Welihindha for his green card — he has been able to remain in the United States through a series of work and student visas.

“We feel now’s the time,” Welihindha told the Blade. “We’ve been together for five years and even though it’s not recognized in South Carolina, we feel [as] though getting married in a place that recognizes us as being equal as everyone else and coming back to South Carolina would be inspiring to the community there. It’s still something we feel is going to have a symbolic meaning to us because of that.”

Wilson and Welihindha are among the dozens of same-sex couples who are expected to marry across Maryland on the first day gays and lesbians can legally marry in the state.

Baltimore Mayor Stephanie Rawlings-Blake will attend same-sex weddings that will begin at Baltimore City Hall at 12:30 a.m. on Jan. 1. Several gay and lesbian couples are also expected to tie the knot in Cumberland just after midnight on New Year’s Day.

More than a dozen same-sex couples are expected to get married at the gay-owned Black Walnut Point Inn on Tilghman Island in Talbot County on the Eastern Shore on Jan. 1. Paint Branch Unitarian Universalist Church in Adelphi will host what it describes as a “wedding reception” on Jan. 6 that will celebrate the same-sex marriage law.

As for Wilson and Welihindha, they said they are both excited and nervous as their wedding day approaches.

The couple had considered tying the knot in D.C. after same-sex marriage became legal in the nation’s capital in 2010, but Welihindha noted “Ryan and I got really excited” about the prospect of nuptials for gays and lesbians in Maryland “because that’s Ryan’s home state.”

“For us, immigration equality is kind of an important issue because my partner is from Sri Lanka originally and came over here to study and has not been able to get a green card. And living in South Carolina our relationship isn’t recognized at all,” Wilson added. “So getting a marriage license from a place like Maryland where I grew up is the first step along a path towards really recognizing our relationship. Of course we want to sort of be ready in case the courts rule in favor of marriage equality. We’ve been looking for the place to do it [and] when Maryland finally decided in favor of equality we decided this was the right time and the right place.”
