An ex..no matter how badly a relationship ends will remember his(or her) love and how much it once meant at least on Valentine's day if not every day of (his or her) life.
Can you give me more details about the greetings?
Because he was lonely this Valentine's, since you left him and all. Even if you don't take him back, he is still going to learn from his mistake.
feeling the memories of a better time?
