McVie left the band in 1998 after 28 years as the group's singer, songwriter and keyboardist, saying she was "just music'd [sic] out."
"I suffered from some kind of delusion that I wanted to be an English country girl, a Sloane Ranger or something ... and it took me 15 years to realise that it's not really what I wanted at all," she told The Guardian.
McVie rejoined the group in September for shows they had at the O2 in London and said she realized how much she missed performing.
"It was amazing, like I'd never left. I climbed back on there again and there they were, the same old faces on stage," she said.
"I like being with the band, the whole idea of playing music with them," she added. "I miss them all. If they were to ask me I would probably be very delighted ... but it hasn't happened so we'll have to wait and see."
