Im abit worried about getting a new puppy with my cat?

I got a puppy recently and my cat is friendly with every other animal and person in the world except dogs!! She soon let the pup know who is the boss and as long as they don't interfere with each other they are fine, the cat even lays by the dogs bed so long as the dog is asleep! Your cat will let you know one way or another if he's not happy but as long as you make the effort to be friendly to him then it should work out fine.
