PLEASE, PLEASE DO NOT tell him your secret, Deniz. I agree with everyone here, he will hurt you. You may not want to believe that, but he will! You have seen the best of him, and he has only seen of you what you want him to see. When you tell him the truth, you will no longer see the best of him.
Break it off now and just walk away. No harm done.
Yes your heart will be breaking, but he could put you in hospital or worse, and the whole town is going to judge you in the worst possible way because they will find out too!
Of course, I would love a happy ending, but I'm sorry Deniz, given his age and how he HATES gays and TGs, he will honestly destroy you as you have definitely deceived him. No happy ending here, I'm sorry.
