Formal:
* Я люблю тебя (Ya lyublyu tebya) - This is the most common and literal translation of "I love you." It's suitable for all situations, but can feel a bit formal.
Informal:
* Я тебя люблю (Ya tebya lyublyu) - This is the same as the formal version, but with the word order changed. It sounds more natural and intimate in informal situations.
Romantic:
* Я люблю тебя всей душой (Ya lyublyu tebya vsei dushoy) - This means "I love you with all my heart," and is a very romantic way to express your love.
* Я тебя люблю безумно (Ya tebya lyublyu bezumno) - This means "I love you madly," and is even more intense than the previous option.
Other options:
* Ты мне очень дорог(а) (Ty mne ochen' dorog(a)) - This means "You are very dear to me," and is a good option for expressing love in a less intense way.
* Ты мой(я) (Ty moy(ya)) - This means "You are mine," and is a very possessive way to express love.
It's also worth noting that Russian culture is generally more reserved than some other cultures, so it's important to be mindful of the context and the relationship when expressing love.
