My boyfriend ruined my first college experience for me

So I just moved cities and I got an opportunity in a good college I was excited and happy to make friends like everyone else . Then I got to meet this guy through my class group he started small talk then we started dating for a while all he did was just rant about how this university is bad and all (it literally has good placements and great teachers ) so I was a little off about that .

Then I made couple more Friends from the class group and he didn’t let me talk to them too in peace he was always jealous and negative . He is soo dumb yet I was supposed to inflate his ego by supporting him in his shit so I lost friends and some of them won’t even talk to me . He has a bad reputation in front of the teachers when got them to think that I am like him too he is castetist , racist etc etc

Now he had blocked without any explanation or warning I tried reaching out to him but didn’t get a reply. Now I don’t wanna go to college and meet him ever again because if I saw him I would 100% slap him across the face

PS : the classes till now were majorly online because of the heat our offline class will start a month later .

The college hasn’t even begun and I am amidst so much drama already

TL;DR : basically he was pessimistic and has a bad reputation which put me in soo much drama and now he has blocked me and I have no one
