Feelings 😰

Last night I broke up with my bf because I knew that we were growing apart just because of the long distance. Also, we are both in a stage of life were we have big priorities with our careers. However, I have been crying after the break up and feeling sad because I feel I lost my best friend. I want to call him to see how he is doing but I don't  want him to think I want him back. Should I call him or not? If yes, when?'
