What does it mean when a guy says you're breaking his heart?

But its not like that kind of breaking his heart...

I was flirting with him and asked him if he understood a reference to a song. He responded with: I do understand the reference, my god (my name) you're breaking my heart. And I want you to know that I have no problem hanging on for the long run with the right person...

Which was random. Does anyone understand this at all?
