Oh my dear, that's a horror you have went through and I personally feel that you have not done the right thing by keeping it a secret, because this will encourage him to do such things in future again if not you then some other girl.
When a girl keeps quiet on any kind of abuse whether physical or verbal, the opposite person will be more encouraged to do it again.
This is the real problem with many women, majority of the time they get molested by their own close family member and in fear of shame or to keep family harmony they become quiet and these cases only keep rising with the silence. It keeps giving them more and more power.
I wonder how do you put up with him after this incident.
My dear my genuine advice to you as a woman, please bring this matter up with your family, do not feel ashamed about it, I feel teary and enraged while even writing to you this comment. You are very young and this is a deep hurt for you which if you do not confront, the pain of it will go for a long way in your life.
I just find it very embarrassing to talk about,however I will put your advice into consideration,thank you for your kind words @nainaztengra
I wish you lot of strength @lenedamag
