I find your definition of the present simple as something being true in the past, present and future 1) far too simplistic and 2) not correct.
If I say "I like apples" then the only thing you know is that I like apples right now. It is possible that yesterday I did not like apples. In two weeks' time, you might ask me again and I might say "No, I've gone off apples. I don't like them anymore".
If I say "I go to the cinema every Tuesday", you know that I have definitely gone to the cinema for several Tuesdays in recent times and that I think that the likelihood is that I will probably continue to go to the cinema every Tuesday. However, you do not know that it has always been true in the past or that it will be true in the future.
Please see my corrections to your post in red. Please follow the rules of written English at all times:

- Always capitalise the word "I".
