I think that he's trying to have a relationship with this new girl, but he's in too much pain from his previous relationship because he keeps looking at the other girl and his being reminded of the girl who broke his heart. I think she might have been deeply depressed and a cutter (if you cut deep/ I might learn). I think he felt partly responsible for taking care of her but the toxic relationship ended in a lot of pain for him, but he's still not over her
