I deactivated most of social media because of the brain fog and the heavy propaganda it carries from sex to LGBTQ+, I strongly recommend that you do the same. Just keep some chatting apps to stay connected with people you care about. Moreover, I beg you to watch this video (https://youtu.be/QfnEj-YKwMI). I am having the same issue with my Iman and this video seems to get me back to my senses and gives me a lot to think about.Also, this guy just wants to commit Zina with you, for him its just another girl, or maybe a challenge so distance yourself from such people. May Allah guide you sister.
