What does hard to please mean?

Anonymous
I've been told that I'm apparently "hard to please when it comes to relationships" by some woman I don't even know, and I actually have no idea what it even means. :/ Lol.

Can anyone out there interpret this phrase and share the definition of this? Lol.

I've googled and can't find the answer. :/ All it tells me in dictionary.com is, "(of persons)" Whatever that means :S

But I've thought about it.

Does it mean that I'm apparently

Clingy, demanding, overbearing, pushy, bossy

Or

Hard to get, arrogant, knows what I want, stubborn

Or, what does it mean? Anyone care to share? Lol.
