How can I confront my dad about this secret?

All my family seem to keep secrets! My mum lied to my brither about his real father! All of my family hide somthing because I here them talking quietly thinking that I cant here! My suspicion began to grow when I found letters saying that my dad has two other sons while he sais I'm his only child! I can't confront him because I'm scared what will happen! If I confront him he might never trust me again for going through his personal things! If I don't it'll eat at me forever! please help!!

just have a talk with your family im sure theyll understand

Ask yourself - Will anything GOOD come from this being revealed ?..if the answer is no, don't do it..use your best judgement.

Good luck !!

well meybe you could just drop hints that you might know so he will be a little less surprized when you ask him. or you could ask your mom if she knows anthing about it. but he may also have a reason not to tell you your mom may not even know and if you told her that could ruin things between them so you might do a little more investigating before you try and confront him

My mum and Dad arn't together, they hate eachother and I don't get on with my mum because she's a alcoholic! The only person I can ask is my dad and I think I might leave it until I'm older
