Falling for you, i would say, is a way of saying "I'm falling in love with you". It also seems to carry the connotation that one is falling, uncontrollably, into love. It indicates the act of the 'fall' into a state of love for somebody.
Don't be the first to say I love you. Wait for him to say it. After he says it you reply, "I love you too" or "I think I love you, too" or "I think I'm falling in love with you." You could also say, "I love being with you."
You can say "আমি তোমায় প্রেম করছি" (Ami tomay preme korchhi) in Bengali, which translates to "I am falling in love with you".
