what is real love?

We're in love for 8yrs...

My boyfriend told me he'll love me only next 10years last night. I was curious about the reasons.
(He usually said let's love 2 or 3years more before.)

He said 10 yrs is long time, and it's enough.
I asked why you always talk about the end and also terms. I was so sad and felt unhappy about his sneering tone.

I am in the hotel room near the airport to wait my flight.
I don't know why he always count our love....so sad and painful...

Any advices?

Maybe he does it just to annoy you? Kinda like a childish prank of his. It's like how an old couple would fight just as a way of showing their love. The fact that he is still in love with you after 8 years and that he sees it lasting even longer should give you some assurance. I don't think you have anything to worry about. I think he is just messing with you. No one knows what will happen in the future, in a way that's what he is really saying.
