As much as I dread it, I know one of these days my baby girl will get her heart broke by the guy she believes she's in love with. I hope instead of crying into her pillow she walks to the kitchen and tells me she needs someone to talk to. I know she'll tell me as much of the story she can before falling to pieces. That's when I'll grab her and hold her. I'll tell her exactly what every young girl needs to know.
He's not upset about losing you...right now anyways. He's probably out with some friends tonight, and if he's a super jerk possibly even out with a new girl. As girls, we tend to want to be alone to get our emotions together after a relationship ends with a guy you love. That's not so much the case with guys. Some guys feel "trapped" when they've been in a relationship for an amount of time. So they go a little overboard with their new found "freedom".
Chances are he's going to post something like "Single and it feels so good" on Twitter or Facebook. Don't post something similar. Let him do what he does because it looks very vulnerable and desperate to ask for attention just because you're newly single. Don't refresh his page over and over. That is so unhealthy for your mental. He's not yours to worry about anymore.
You don't have to delete his number, messages, and all his pictures right away. Give yourself time. Don't sit around and weep about things that remind you of him. Removing things about him from your life can wait a day or two. Right now mending your heart is a first priority.
That first week after a break up is devastating. Everything will remind you of him. And that's okay. Because you can't forget the way they held your hand, the way your name sounded coming out of their mouth, the way they know how to make you laugh so hard your stomach hurts. Though you can't forget those things about him you can remember other things about yourself. Like how much you enjoy reading, running, painting, etc. My point is don't let his absence make your life seem gray. You were happy before him and you can be happy without him.
You'll need one good cry. I've learned that with anything that hurts you in life. Cry long and hard one good time and then never cry about that particular situation again. Surround yourself with friends. If you don't feel like you have any, it's probably because once you got a boyfriend you pushed them away. Go to them and apologize, if they are true friends they will forgive you and be there for you like they once were.
No one tells you this but all through this life you will grieve the loss of people still alive. As hard as it is to believe, you're going to wake up in a morning in the not distance future and he won't be the first thing on your mind. You might shower, eat breakfast, start to do your hair and realize you haven't thought about him. And you'll almost feel bad for slowly getting over him...don't. Embrace the joy of moving on. Live your life and love yourself.
