pain of being happy (part 1)

I can't breathe,I can't sleep,I can't eat but why because I watched my boyfriend leave me in a quick flash of a wink...he told me he loved me and promised me he would never leave but he left for another girl...he moved on happily while I had to suffer and endure the pain..he couldn't wait for me to accept that its over he just left with no thought and no heart....someone once told me a promise is to keep and not to be broken and thats true why would they call a promise something thats unbreakable if u always breaking it ?...the fact is he moved on in a second and I suffered and watched him be happy..what selfish man does that...takes someone's happiness away and gives it to someone else..not once did he look back to see if I'm okay or made sure I'm safe but he laughed and took a girl that he didn't even know because she had a figure better than mines...he walked out that door with pride and happiness while I walked out that door with tears and brokenness...shattered and torn apart ,blades all over,mascara running thru my cheecks from eyes to clothes all wet with tears...no one thought was I okay all they did was tell me move on...like its easy to leave someone you been with so many years
