Whoa, okay. I'm sorry I didn't have the time to respond to everyone yesterday, but I did get to read all of your awesome posts which were so, so helpful, and I was all encouraged and determined to be friendly the next time I saw him and everything, but... well, I probably should've mentioned this earlier.
His friend/the girl he was dating (an ENFP, meep) is still interested in him, and is apparently still trying to win him back. This causes a vast and terrible mix of emotions in me, but they basically all sum up to me feeling horribly sick whenever I see her or think about her (this is of course multiplied tenfold when she is with my ISTJ.) I am extremely paranoid about them getting back together, and it's always really hard to tell whether or not they have because they have remained close friends, and she likes to flirt with him (which he doesn't seem to discourage, but I am not sure if this is because he doesn't mind or because he is simply not receptive to it.) She has a huge advantage over me, a, being an ENFP and therefor naturally more compatible, and b, being able to talk to him whenever she wants to without feeling nervous. (This I am WILDLY and exceedingly jealous of.)
And like I said, I was really ready to talk to him today. But she was there. She doesn't have our first period (I'm afraid that this is a high school situation... which I'm sure has everyone rolling their eyes, I'm sorry) but she was there... waiting for him. (It's an elective period, so it's sort of permissible for random kids to just come and hang around.) He was uncharacteristically late today, but she went up to him once he arrived and was all "woo" and I was all "kill me." And it was kind of like that.
But besides the primary emotion I feel for her, which I will concede is hate (I tried really hard at first not to hate her, but... I just can't help it) she also fills me with the most painful sort of guilt and empathy, because I know exactly how she feels (assuming that she actually loves him and is not just infatuated) and somehow, even though I can't stand her, I feel like if one of us should suffer through the excruciating pain of unrequited love, it should be me. I can't help but immediately come to this conclusion and back down, even though I know it is ultimately the ISTJ's choice! D: And then there is of course the guilt that comes from hating a perfectly nice person... it's awful.
She asked him to go to this dance with her (it's a formal dance that I guess you could say is kind of specific to our school? It's not the prom or anything but it's about as important.) and he said yes, so.... I feel horribly discouraged and just generally sick. I know this is in the SJ forum, but does anyone know how hard it is for an ENFP to get over unrequited love? Is it as hard as it is for an ISFJ? Do you guys think I actually have any serious competition with her, considering that he was the one to end their relationship? :c
