Jessie Reyez - Figures Lyrics Meaning

i fel like this song is about giving your all in a relationship and getting nothing in return, and when the relationship ends he's gonna realize what he gave up and that he made a mistake, but she's not going back to him. also i feel like she is saying that she doesnt want to feel hurt by what he did but she was/is in love with him so she can't help but feel hurt
