Once the Feeling Is Gone

"Once the feeling is gone, it's hard to find it back..."

I watched the final episode of the Chinese drama series at TV Ch 8 last night. Thie above statement was said by a male character to the gal he once loved but who had rejected him yet she wanted him back now. A sad but factual statement indeed.

Friend C told me the same thing recently, i.e. if his ex-gf wants him back later (just broke off recently) he will not give her a second chance. Not sure if he is being MCP or he has never loved her enough.

This goes back to the question on what is love? Is love just a feeling?
