"Your too nice" Is this BAD to be these days?

I got home after all day shopping for Christmas gifts. I grab a bite to eat then call up this gal I've known for 3-4 yrs now and we talk about Christmas and what I bought today.

Then that's when she says to me "welp, you know you're just too nice of a guy" and shortly afterwards the conversation ended.

I guess I dunno if I should take this as a compliment or not? I've heard this throughout my life and sometimes I wonder if being a nice person isn't "socially accepted" anymore?

Maybe I'm making way too much outta this, but I've heard many people that have also been told they have this "Too nice of a guy" problem...and break up for this strange reason.
