What's love

What's love? A good question. What's ur reaction when someone told u he/she love u? Do u believe it?
Mark text me again n' told me he love me yesterday evening. I don't know why. A single man who works in another country feel lonely n bored frequently,I guess. And if he's a gay,we all know that there's nothing he need except sex.Honestly I really don't care it because I don't loved him.We all just need sex,right? Don't lied to me,ok?
