I don't believe you can be too nice at all !
I've never ever gone for the bad boys .. never been at all interested. Some guys who I thought were nice treated me badly but i've never intentionally gone for a bad one
On the other hand I couldn't be with a guy who was like a puppy dog, never disagreed with me and was a wet blanket .. that would drive me up the wall
Desmo has the perfect balance. He's kind, sensitive, looks after me but at the same time he's his own person and if he thinks I'm wrong he'll tell me !
You should never change who you are .. you'll find someone who does love for you who you are
