can feel myself falling for him, but he drives me up the walls??

[stretchmark]

He makes me laugh, keeps me on my toes, makes me feel special...yet winds me up a treat!

Is that a good or bad thing??

Depends on the level of winding up you mean I suppose. Playful banter is fine. Pushing your buttons to make you feel bad about yourself or winding you up like some kind of power trip is not so good.
