So I'm in a weird situation.

So according to my friends I'm straight (17y M) But for the last 5 months I was with a guy (20y M) but I was also crushing on my best friend (18y F) and it's like I don't know. I'm super confused the guy I was with really messed me up. Like 5 months of my senior year I spent with him and he just left me. And my best friend has been with me for the whole break up and she talked through it all with me. Like what are some ways to move on. También I'm not openly Bi-Sexual. I will probably never come out. Because of the career choice I plan on going into.
