When a girl's boyfriend is emotionally distant/abusive, and she doesn't want to just end the relationship, she may seek the comfort of a co-boyfriend. The co-boyfriend hears her complaints, and this allows the broken relationship to continue on a bit longer.
Trina's boyfriend doesn't listen to her problems, so she talks to her co-boyfriend Jack about how shitty her boyfriend is instead of just DTMFA (dumping the motherfucker already).
