<human>: Alright where do I begin, Ive been dating this guy since I was in grade 10, and he was in grade 12 (3 years). We've had our ups and downs and are arguments mainly stem from jealousy on his part. Basically any relationship with a male makes him feel threatened. I lost all my male friends since dating him because he's jealous. Last night we went to a local pub with live music, my good friend invited us out. We were drinking and eventually moved seats with me and my friend sitting in the front row of chairs and him sitting behind me (on his own accord, as he could have easily pulled up a chair next to me). I asked him multiple times to sit next to me because he was awkwardly behind us by himself. He refused. At the end of the bands set I turned around to talk to him and he was visibly pissed. I asked him what he wanted to do and he replied in a cynical voice about being ignored and not giving a fuck and to keep ignoring him. My friend was obviously put out. He proceeded to get angrier and was like why would you even get me to come you just wanted to gawk at the musicians and whisper. At  this point I hugged my friend bye and was like ok Im gonna leave now. I leave he follows me and we proceed to get in a huge fight about how we were whispering about guys and I ignored him. He threatened to kill himself because I obviously broke up with him. This isn't the first (or worst) episode of public jealousy that has left me extremely embarrassed. Im leaving for a 3 month internship in 2 weeks. Its hard to stay broken up.. hes my best friend despite this flaw. He doesn't understand that he is in the wrong, and today got mad about 2 guys that liked my picture that I met 3 months ago. He's gotten somewhat better but I just don't know what to do, he's extremely difficult to break up with (I've tried before), and says I'm all that matters in his life and with out me he's nothing.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Boyfriend is extremely jealous of girlfriend of 3 years, so much that I cant take him out drinking because he could cause a scene.
