If you are responding to someone who has said "I love you":
* Я тоже люблю тебя (Ya tozhe lyublyu tebya) - This is the most direct and common translation, meaning "I love you too".
If you are expressing your own love for someone, but they haven't said "I love you" first:
* Я тоже люблю (Ya tozhe lyublyu) - This means "I love too", but is more general and doesn't specify who you are loving.
Other options:
* И я тебя (I ya tebya) - This is a shorter and more informal way to say "I love you too" and is often used between close friends or family members.
* И я люблю тебя (I ya lyublyu tebya) - This is a more formal way to say "I love you too" and is often used in more serious contexts.
The best way to say "I love too" in Russian will depend on the specific context and your relationship with the person you are speaking to.
