'Everybody says I love you'. Analysis of declaration of love

Ludwig Wittgenstein's and John L. Austin's studies have offered a new concept of language. Should one, in the light of 'The Philosophical Investigations and How to Do Things With Words', limit himself or herself exclusively to investigating the manner in which feelings are spoken about, whilst remaining tacit as to the very nature of feelings? Can love be talked about using the language of analytical philosophy? The author's quest is one for giving replies to those queries; to this particular end, declaration of love is made subject to detailed analysis from the standpoint of Wittgenstein's concept of linguistic games and Austin's speech act theory.
