How to select columns from different rows that share a common column value? [closed]

Given the following table setup, how do I select the meta_values from both rows that have a common post_id?

I'm looking to return something like:

Bob is married to Jane
Pete is married to Amanda
Rick is married to Sally

+-----------+------------+--------------+
|  post_id  |  meta_key  |  meta_value  |
+-----------+------------+--------------+
|    10     |  'key_1'   |    'Bob"     |
+-----------+------------+--------------+
|    10     |  'key_2'   |    'Jane'    |
+-----------+------------+--------------+
|    20     |  'key_1'   |    'Pete"    |
+-----------+------------+--------------+
|    20     |  'key_2'   |   'Amanda'   |
+-----------+------------+--------------+
|    30     |  'key_1'   |    'Rick"    |
+-----------+------------+--------------+
|    30     |  'key_2'   |    'Sally'   |
+-----------+------------+--------------+

Thanks in advance for your help.
