Self-sabotage

I will lose you I know that for sure Because who, in their right mind, would stay and endure? I will lose you I've guarded my heart But though I know it's coming It will still tear me apart It will tear me to pieces The day you decide to walk away And each night, I imagine Begging you on my knees to stay But I will not waver I will happily let you be Because who, in their right mind, would stay with someone like me?
