Will u be able to have a good social life

Hi, I’m a 16 year old gay guy who has been thinking about moving to Croatia for college, specifically Zagreb.

What I want to ask is if I’m going to be able to find not only a partner, but also friends and acquaintances my age at college that i can hang out with and form really close friendships with while being able to fully express my sexuality (with straight people specifically). Basically what I want to ask is if I’m going to have any problems with making friends due to my sexuality whether it be homophobia or anything else in a similar sense. If that’s the case, please drop any advice you have for me and have a good day. Thank you?
