Do 당신 think this is bitchy?

당신 should both compromise about the situation. at the road you're going down you're not gonna have this friend of yours anymore. tell her 당신 just wanna talk to her a little more, and if she continues ignoring 당신 keep trying to get closer, but don't go overboard on it all.
i'd also suggest apologizing about calling her "pathetic" and that remark 당신 said after she blamed 당신 for almost committing suicide
this is ultimately your decision. i'm only giving my small outlook on the situation.

tell her 당신 r making no sense thats what i would say

Well, I think 당신 should apologise. 당신 don't know why she was ignoring 당신 - in fact, 당신 don't know if she was ignoring 당신 at all. There could have been something huge happening in her personal life that she was dealing with 또는 she could have been working on revision 또는 homework. But 당신 assumed she was ignoring 당신 and your natural response was to 암캐, 암 캐 about her, which is completely unfair and has obviously really hurt her feelings, enough to make her consider suicide. And then, instead of apologising 또는 even saying 'Don't commit suicide' 당신 completely disregard her feelings.
Really, 당신 are in the wrong here, so apologise.
