Love child

How to Tie a Clove Hitch on a Post

How to Tie a Brummel Knot

Absence makes the heart grow fonder

Joined at the hip

Puppy love

Walk out on

Love nest

Wear heart on sleeve

Labor of love

Only have eyes for

Head over heels

Pop the question

The love of one's life

An item

Match made in heaven

All is fair in love and war

The course of true love never did run smooth

No love lost
