On 21 March 2022, through a social media for promoting the song, Sheeran said that he and Balvin met in a gym in New York in 2021, which led to them having lunch and coffee and tea together that day, and then started chatting with each other. He was performing shows in the area for Christmas at the time and the two artists met up in a recording studio and wrote "Forever My Love" and "Sigue". Sheeran added that "it was a proper challenge learning Spanish for this and I had so much fun doing it". About collaborating with Sheeran, Balvin stated that "I wanted him to come to the world of
reggaeton and he invited me to his world as well" and "it was really cool hearing him in Spanish and we hope that you all love the songs as much as we do". Sheeran was also interviewed by New Zealand interviewing channel
Project NZ the week before the release of the songs and referred to his next release as "something else that's a bit more of a curveball" and that it would be releasing in ten days, but added that "I don't think it's gonna be a massive hit in New Zealand though" and "it's more gonna be a big hit somewhere else", giving a hint by stating that "when you hear it you'll understand". Writing for
Billboard, Jason Lipshutz felt that "J Balvin and Ed Sheeran are both global superstars adept at crafting club-ready
pop and heartfelt
balladry, and on a new collaborative two-pack, the pair delivers two sides of their artistry while feeding off one another's energy" and "Sheeran sounds confident crooning in Spanish", adding that "Balvin offers bare emotion on the strumming sing-along" song. "Forever My Love" is a
pop ballad that is set in the key of
