Hi farooq,

I am not a native speaker, but I can help you with some of the idioms you stated (most of them can be find on Google:

A: tie the knot = get married
B. hava a crush = be infatuated with someone
C: take the plunge = to begin an unfamiliar venture, especially after hesitating
D: fall in love = to begin to love someone, to become strongly attracted to a place, activity, or thing
E: on the rocks = likely to fail because of serious problems; in a state of difficulty, destruction, or ruin; without money; bankrupt; and also served over ice cubes (alcoholic drinks)
F: head over heels in love = to be in love with someone very much, especially at the beginning of a relationship
