To me, it's saying how she loves someone that much, that she can't stand by and watch them be hurt by her. or be victim to her. She has low self esteem and believes that she's going to continue hurting that person if she stays with them. Her lover worships them but she's saying how they could do much better, and they've been through so much that they should understand that she's not right for them. At least that's what it's like to me.
