highschool boy problem

okay so I’m a sophomore in highschool and in late sept I started to really like this boy, a freshmen, lets say his name is nate. at one point I was told nate liked me, but he never made a move or anything so I tried to get over it. around late december nate’s friend and I hit it off and we had a thing for a little, but never dated. a few months later…I hooked up with a senior who is best friends with nate’s brother (yeah I know I dug myself a hole). I was hoping that through the past months (it’s probably around march now) I would have gotten over nate..but I havent. so he eventually found out that I liked him and he didnt really do much about it. since I didnt want to waste my time, I decided to build up the courage to..atleast text him..and find out if there’s a chance or if I should just try to get over him. turns out he said that it wouldn’t work because I had a thing with his friend and his brothers friend. I was hoping it wouldn’t have come to that, considering in highschool tons of people date within groups and stuff. but since it did I had to try to get over it. we both decided not to make it awkward..even though it absoluetly was. HOWEVER, this weekend we ended up hanging out for the first time since the awkward conversation and I had a lot of fun and we hit it off well. I don’t know what to do…should I go for it again? or..I don’t know move on?

oh also, he was flirting with me and my friend a lot..who was flirting back even though she knows I really like him…
