The couple live about an hour outside Boston, where they're raising Josh's 11-year-old disabled son from his prior relationship.
"Connor has a condition called septo-optic dysplasia," explains Pamela. "He is blind, cannot walk and can only say a few words. He has the learning capacity of a 2-year-old, is on several medications and needs constant care."
Despite the challenges, "I could not imagine my life without Connor," says Pamela.
Another setback: "For the first two and a half years of our relationship, I was either in Iraq or stationed in Fort Bragg, North Carolina, while Pamela was in Massachusetts," explains Josh.
They can't "afford the wedding of our dreams, but standing up to say our vows in front of our friends and family is the most important thing to us, no matter how we do it," says Pamela, who wants to say "I Do" in Boston. Expect traditional, along the lines of Jessica Simpson and Nick Lachey's classic 2002 Texas nuptials. "Their wedding was romantic and elegant," says Pam.
