Why you always says something like "You are my first and you will be the last"

Tweet

or something like "There was no one after you in my life". How did you react or think when he/she says that? Is it a normal conversation that actually used by a men to his woman, agreed? And will be it just like when a girl ask a guy "does this jeans makes my a** look fat", you will automatically say "no" or like when you accidentally hit someone shoulder when you walking, you say "sorry" or DO you actually really MEAN it? Honestly, have you ever used this phrase to him/her? Sharing is caring.
