I will use one word only but for different stages of love.

  1. Initial honeymoon phase : Ecstasy
  2. Late night chats phase : Connection
  3. Divergence phase : Trust
  4. Real love beginning phase (If love survives long enough.Most sperms die off till this phase) : Peace
  5. Fighting phase (After real love also their are lot of issues to be settled) : Headache
  6. Love completion (accomplishment) phase : Bliss and enlightenment.

Till phase sis arrives our mind shall always search true love,ever.
