@poojasa432. Welcome. This is such a difficult situation that you describe as ultimately he has been leading you on with spurts of attention to keep bringing you back. There is something in that for him but I don't think it seems healthy for you. You did not mention your age or his age.

Have you talked with your friends about this? Or a therapist? When it comes to relationships it's not always easy to say "no" and then move on. Something within is keeping you hooked into this pattern with him and it would be good for you to figure out what that is.

Do you have a mental health therapist to talk with? A school counselor?
