If you're lucky enough to have a French person say 'Je t'aime' to you, you can be fairly sure that love is in the air. For a more everyday 'I like you', French speakers tend to say 'Je t'aime bien'.

Je t'aime beaucoup = I love you very much, Je t'aime bien = I like you We use aimer bien when we are speaking to a family member, a friend. A person can say : je t'aime, to a very, very close person, a spouse, a fiancé, etc.
