Hi Dear I don't know how much you contribute to the whole scenario, or you are taking all the blame on your self. Try and look out why this incident happened, and if it is genuinely your mistake, try and explain them, if they are your true friends they will understand. Try not forcing pressure on them to get back to conversing with you, leave decision on them, as if you force, it can go against you. Try and do good things, something to mend your mistake(if it's actually your mistake).
