Seeing the end of a good thing

I'm posting this not to vent, but really as a warning. I met my (now ex) boyfriend and we moved very quickly. This, in and of itself, was not particularly bad and we certainly cared about each other. I allowed myself to become so concerned with us being together that I became a cunt, I stopped trusting him and let myself become a monster. The night I accused him of cheating was the night I ruined my relationship.My warning in short: don't break something good because you can't deal with your own insecurity. When you see it, take a break there, or lose the one you love forever.
