The song is quite relatable and I feel most women have been there at some point in their lives. You know...that time when you meet that one guy and all is well at first then things go south but you still keep going on and you have this unhealthy dependency/situationship that noone is ready to leave even though you want to and wish you could with every fiber of your being. I always call that guy the "Mr. Big" of your life. For those who know me, I really disliked Mr. Big. I didn't think he was nice to Carrie but no matter how hard she tried she couldn't shake him off. Ultimately, it worked out for them because TV but for the most part it's really not the case.
I often wondered if it was better or worse for Selena that she met her Mr Big young. I am leaning towards better because there is enough time to get over him but at the same time she is still young and figuring herself out that might make it harder to deal. Anyways here's the song. Below is the monologue she gives before the song starts. Let me know what you think.
