XOXO is often used to express affection or love in text messages, emails, and cards. However, if you want to mix things up a bit and avoid using XOXO repeatedly, there are a few other options to consider. Some common synonyms for XOXO include hugs and kisses, smooches, snuggles, and cuddles. Other options include terms like love and adoration, such as "love you lots" or "adore you endlessly." For a more playful or flirtatious tone, you might try using terms like "be mine," "sweetheart," or "darling." Whatever synonym you choose, make sure to express your affection genuinely and authentically.
