NEED ADVICE!Please no hate!

So this was me in June. And I was naïve and stayed with him and now I don't know what go do. I haven't told my parents cause I've been scared. But this whole situation is eating me alive I think about it every day and i try to talk to him about and doesn't seem to understand why it hurts me so much. No one should have a fear with someone they love and that's the worst part is idk what i would do without him in my life. Im so lost. Someone help me figure out what to do. Do i tell my parents? Please help!
