Regardless of whether Mr. Big is all he (and his member) are cracked up to be, your partner sounds like a dick - and not the fun kind. Suicide threats? Attempts to sabotage your personal and professional relationships? Emotional abuse and put downs? In the words of Whoopi Goldberg's character in "Ghost" - "You in danger, girl." I hope you can leave your narcissistic partner far behind and seek out someone who builds you up instead of tears you down. You deserve better!
