Head over heels: Deeply and madly in love
Love at first sight: Falling in love immediately upon meeting
Tie the knot: To get married
Apple of my eye: Someone who is cherished above all others
Match made in heaven: Two people who are perfect for each other
Pop the question: To propose marriage
Wear your heart on your sleeve: Making your emotions and feelings very obvious
Love is blind: When you cannot see the faults of the person you love
