It's a sweet thing being in love. That feeling of comfort no other person can give but the person you're in love with. But the amount of love you give will also be the amount of pain you'll feel when it's over. The first stage will always be crying, crying so hard because no one else can make you feel better but that person who left you. Second is regret, regret because you did things that you shouldn't have done and you can't do anything to take it all back. Last is reminiscing, all those things that you two made and promised that will last forever.. And that cycle never ends until you wish it to.
Crying will always be first because eventually, it will go on for the whole duration of your pain. Imagine crying at night quietly because you don't want anyone to hear and the only thing that's with you is your iPod. Lol, that could be funny but it's true. Crying is the only way you can make yourself feel better than doing other things stupid. It works because the heaviness you feel in your heart lessens, but it doesn't take it away fully. But it helps.
When you get tired of crying, and you will for sure. You will regret. Regret a lot of things, part of it will be the fact that you said YES to him in the first place. You would tell your friends that you regret saying YES to a complete jerk who fooled you all along and you're friends say "You're saying that because it hurts." and you know their right but you deny it because in a way, you know you mean what you said. It's dumb really, regretting things in the end. It really is.
And when you're fed up crying and regretting things, when you're mind is already quiet, you reminisce. Things that you did that you cherish and wished that would've lasted until the very moment you're thinking about it. Things that you thought you forgot will come back and it'll just stay there bugging your mind until you cry and regret again. Just like I said, it's a cycle and it will never end until you wish it would.
In the end, when you've moved on.. All you would do is laugh about it. Laugh because you've been a complete idiot doing all those things just for one guy. But even if you were laughing and you've moved on, the feeling of sadness will still be there. Just covered by a huge happiness and realizations that wont come unless you've completely forgot about him.. It's a long process, but everything is.
