I'm not sure, but I don't think so. Affectionate is an adjective, meaning that must be followed by a noun or a preposition
I suggest that you say: I am very affectionate toward you.
How about spell check for "garmmer", but I agree w/F.S.'s alternative however, having said "I love you", I really don't think it necessary to follow with "I am very affectionate toward you".
