* J't'aime beaucoup. (pronounced "j't'aime bo-koo") - This means "I love you very much."
* Mon cœur. (pronounced "mon ker") - This means "my heart" and is a sweet and endearing way to express love.
* T'es mon tout. (pronounced "tay mon too") - This means "You are my everything" and is a very passionate way to say "I love you."
It's important to note that Cajun French is a very expressive language, and the best way to say "I love you" will depend on the context and your relationship with the person you're speaking to.
