I think you can make an argument that Rey has strong fears of being abandoned. You can allude that to the fact that she prefers to live a solitude lifestyle on Jakku, as to not risk being in a situation where she would feel abandoned or betrayed by anyone. It could be why she was hesitant at first to have BB-8 stay with her for the night.
Fast forward to the scene at Maz's pirate hideout, Finn tells Rey he can no longer come with her on her journey. Rey then tell's Finn "Don't go." Right when Finn exits the doors, Rey begins he hear the force calling to her. Her memory as a child is herself yelling "Don't go!" as the ship presumably carrying her family flies away. I don't think the writers merely saw those lines of dialogue as coincidence. Finn leaving triggered her hidden fears of abandonment, which allowed the force to call to her.

This is from ESB when Yoda describes the force to Luke. Yoda said you can feel the light side of the force flow through you when you are calm and at peace; much like Rey was when for a moment she closed her eyes during her battle with Kylo Ren.
Similarly back at Maz's place, Rey felt the force calling to her but this time through her fears.
I don't think Rey's character is as clear cut as it seems. I feel she has hidden conflict that will be divulged in the next episode.
