Whether you simply say je t'aime, or you use a longer phrase, you may just be surprised by how powerful the effect of the French language can be.
In French, the phrase je t'aime may also be used to indicate deeper affection, so you may want to choose another phrase if you're speaking to someone you think is nice, but you don't want to imply a romantic relationship.
