Welcome to the forum Maria!
I left Islam 2 years ago because I was in a serious relationship and my religion was pretty much offensive to him.
He brainwashed me enough to consider leaving and actually fully HATE Islam and what it stood for.
This is actually wut began my questioning about religion.
He didnt brainwash me or anything, but since he wasnt Muslim he kinda got me to think about other religions and then research.
My (ex) bf just plainly hated Islam and would constantly mock it wen ii was Muslim.
He obviously was just hateful, it wasnt even anything about rationality.
But anyway,
When you really push what everyone else around u taught you aside, and u question wut YOU believe, is wen u find the truth.
At least thats how it is from my end.
I stop listening to everyone else, and actually thought "....do I really believe this and everything that comes with it?"
But yeah, again, welcome to the forum.
Enjoy ur stay!
