Not telling your friends about the breakup?

ok well first you have to ask ure self if u can tell ure friends about ure break up are they really your friends and are u sure u can trust them because that's big new and something that ure friends should usually in normal situations help you out and get through it because that's what they're there for, are you also not telling them because of what they might think or that they might laugh at you because again if that's true then they're not ure friends
