How packet is forwarded in same network?

Suppose there is sender A and receiver B. Data will come from AL->TL->NL->DLL->PL of A, then A using its subnet mask and  IP of B will check the NID of B according to A. If NID matches then A comes to know that they are in same network. Now A will broadcast HID of B and get its MAC (ARP) and then forward it.

Now at B it will check from NL-> TL-> AL.

Is this correct? If yes will TTL field will be decremented at B as it hits the NL?
