Is it wrong to be over complimenting to a girl? I'll admit I'm a nice guy and I say nice things to a girl I met on the Internet know she said its annoying and I want to understand why being nice is wrong. Before when we first started talking online she said I was different to her friends and I was nicer than the, and she liked that. Why would she change her mind? I want to be plutonic friends with her don't friends says nice things to each other? Even if we were in a relationships din't couples say nice things to each other?
