Lots of boy issues

Lilli
Ok in a nutshell, I used to date this guy (we will call him guy 1) and then there is guy 1s bestfriend (guy 2) ok so guy 1 and I dated for about 9 months but we were on and off a lot and before guy 1 asked me out, his best friend guy 2 told me he liked me but soon after guy 1 asked me out guy 2 said "it was just a joke" and I thought it was a joke until guy 1 and I broke up and guy 2 was there for me and told me that guy 1 was a jerk for breaking up with me. After they guy 1 and I got back to get her but shortly he broke up with me because of a dare that guy 2 made (they were playing truth or dare and guy 2 told guy 1 to break up with me) and so he broke up with me and guy 2 was there for me again. Then guy 1 and I started talking and then we got back together for good but started getting threat text messages from anonymous and when ever guy 1 and I would talk about it guy 2 would act weird, wouldn't say anything and walk of and guy 1 didn't notice anything but i thought it was a bit weird. (Oh and the threats were just telling guy 1 to break up with me and how i was so much better than him and then anonymous said that he would fight guy 1 and to meet him at this place and when we all went (me, bestfriend, guy 1 and guy 2, I realised that it could be guy 2 because technically he was there at the place) anyway later on that year guy 1 and I broke up because we were moving schools and it was too hard to maintain a long distance relationship but guess who was moving to the school I was moving to, guy 2! And all of last year I started liking him but then he turned into a fuckboy and became a jerk although at party's when he's sitting with girls and I was sitting with guys and girls and one guy pulled me away he stood up and got a drink and started talking to the people that were close to the guy and I, but I wasn't really taking much notice of it. Anyway recently I walked into a class and his friend just threw a paper ball that nearly hit me and then as I keep walking I here guy 2 say "that was perfect timing" and I was confused about that and sort of angry so at the moment when I walk past I do a subtle like elbow to the stomach but not that big that he will complain and I have also found that he stares at me quite a lot.
Help what should I think?? Comment below 
I said "nutshell" but apparently that story can't be put into a nutshell so sorry is so long
