How to accept breakups

I just recently got dumped by my boyfriend. It was actually this morning. He did it over snapchat, like a real man. He told me that he didn't see our relationship working out because we don't have enough time for each other. I do sports so I'm unavailable for an hour after school and then I'm free. He works only 3 days a week. I don't see where the no time came into play but let me tell you how I'm coping with this. At first I was mad I posted really salty posts on my spam Instagram account and was basically saying 'fuck him'. But then I started thinking, I shouldn't be acting like this. He really is a good guy and he has a good heart. So I deleted all the posts and made a new one. It said that people come in and out of our lives, that's what happens and we have to learn to accept it. Just because things didn't work out in a romantic way doesn't mean things can't work as a friendship. You have to learn to accept challenges and misfortunes that come your way because that will make your life a whole lot easier. Don't waste your time being upset and sad about the situation make the most out of it.
