Stuck Between Two People

So I’m in a relationship but I also have feelings for someone else.

To start with, my boyfriend and I started dating officially in February. We go to school together but we never really talked until January where we started going on voice calls on discord. Yes, I know, we only have been talking for a month but we would talk ALL the time. As in, we would talk til late at night and sleep on the call and stay on the call til we get to school. It felt like a long time and we caught feelings quickly. We have so many memories together from going on dates to him to us napping in his car to eventually crashing the car (oops) to spending his birthday on quarantine.

But, because of quarantine, I started talking to a friend from school. Mind you, we were just talking, no flirting or anything like that because he knows I’m in a relationship. I found out a lot stuff about him and he learned a lot of stuff about me too. We have so much things in common and it’s so easy for me to talk to him. We would watch movies together through discord and we started talking all day as well. Through time, instead of me going on 18hours+ calls with my boyfriend, I would call him instead. He caught feelings for me and eventually, so did I.

Now my problem is that I’m still together with my boyfriend and I still love him very much, but this person I’m talking to is also making my heart feel very conflicted. And I don’t know what to do because I don’t want to break up with my boyfriend but at the same time, I know it’s hurting my friend that I can’t be with him and I don’t want to keep hurting him.

Please give me some advice.
