So sorry about the negativity. But this is most likely what happen at the end of a relationship, however healthy and happy it is. I am not saying this because I'm broken hearted or what not, but mostly because it is just so funny to see this picture and remember the days when you say all that nasty stuff about an ending relationship. It is normal to say shits about it or become frustrated because of it, as long as you know the limit.
Be glad that your relationship ended, not because you're a jerk, but because mostly it happens for a better reason.
Have a happy Monday :)
