You could be forced into a partnership with someone you don't know well: or don't like very much. Unfortunately, you can't change the situation; you can only get used to it. Summon your positive attitude and work on finding a bright side to this arrangement: because there is one. Volunteer to take on tasks that you enjoy and can work on at your own pace, without your partner's interference. You may find yourself moving into an introverted mood, but that's okay.
