Break-ups are tough. You need to just leave him alone for now and not force him into talking to you or about you.

Given the time and space, in a few months, he'll be good as new and will have moved on.

You should tell him that you 2 can still be frinds let him know that you were protecting him from becoming even more hurt in the future. He will understand

Breakups hurt. Most people go to no contact after they break up, so that they can move on, get over the person.

Leave him alone. Tell your friends to leave him alone. If he decides he still wants to be friends, he'll let you know. Until then, he needs time to heal, and having you approach him, or having people constantly talking about you to him, won't help.

You are 12!! You shouldn't even be having a boyfriend at your age. And this is part of the reason why. Children don't have the emotional maturity to handle romantic relationships.

YOU need to do nothing. This is HIS problem. If you want you can talk to his parents or friends and ask them to help him understand that life goes on and he is too young to get this emotional. But other than that, there is nothing that you can or should do.

You should however, stop having boyfriends until you are older and you can cope better with the issues of a romantic relationship. At least another two years.
