Crystal - Crystal is Tamara's ex girlfriend and first love. The two were together until Crystal flushed her medication and left Ohio without a word to anyone, not even her girlfriend. The two haven't seen one another since, not until Tam turns up on Crystal's doorstep in Staten Island, needing a place to stay.
Elizabeth - The two met and clicked right away, but Tamara is not a good influence on her at all, often encouraging Elizabeth to party and drink, rather than studying or focusing on her career path.
Erika - Tamara and Erika initially met when the two were in rehab together. They got on very well and became close, sharing multiple stints in rehab. Eventually, feelings developed and they began to fall for one another. When Erika got out first, she promised to write and visit Tamara, but she never did. They didn't see one another again until they were both living in New York.
