Emotions suck

It's been months since me and my ex broke up but for some reason today all I've been able think about is him and how we used to be... I had been doing really good and not really missing him all that too much. And definitely not crying since the day we broke up but today I just can't stop... all I can think about is all our good time and even when I try thinking of the bad it just ends up reminding me of how we made it work. And I miss it so bad....
