So it's like blue hair decided that all she holds dear to her or important comes to nothing in the end and so it's why she doesn't even take good care of herself presently,blue hair must feel like if she dares to care about something or someone they will leave or she she loose everything again & again so it's why she accepts to just have sex with pink hair and agree to her terms of not dating
And so blue hair feels safer emotionally.
As for brown hair,well blue hair gets emotional support from her which is why she always comes back to her when brown feels blue pissed her off,blue is afraid to loose brown more than pink and pink sees brown has a greater hold on blue's heart than pink does.
Home girl from her high school wasn't a true friend because she didn't even visit blue at hospital or talked to her about the rumors but made it worse behind blue's back so blue in present won't trust anyone and always have a fear of being hurt and left so in conclusion...blue is just doing what ever feels good and forget about romance because to her it all don't even last anyways.
