Nice... what an awful word

The word 'nice' has a few meanings. As taken from the Free Online Dictionary the following are a few of them,
Nice - adj. nic·er, nic·est

1. Pleasing and agreeable in nature: had a nice time.
2. Having a pleasant or attractive appearance: a nice dress; a nice face.
3. Exhibiting courtesy and politeness: a nice gesture.
4. Of good character and reputation; respectable

Well, on the surface the word sounds 'nice' but then, I never ever want anyone to label or call me nice. Nice is the word one uses when trying to breakup with someone (and trying to spare their feelings)

"My dear darling.... I just have to tell you... it is me, not you... you are a nice person. It is all my fault, I am not right for you. I am sure there is someone nice out there for you"

Damn...How I hate to hear those lines. It is so degrading and irritating... What does one means that a person is nice? A person is nice but not good enough for him or her. It is quite perplexing when I know its 'official' definition but then understand too well its common usage. To me, being nice is when people are implying that you are too ordinary, too common, not special etcetera, etcetera... and I can go on and on...

Well, how do one break up with another. My awful suggestion is just tell the truth. "I am so sorry, you are not THE ONE.... Goodbye". At least if someone say that to me I will not be as crushed as if some one starts the sentence with "Lynn, you're a nice girl...blah..blah..blah"
