i'd say give her at least 2 weeks for her. i know it's really hard, but if u really love her, then u should wait. i suggest u should text her like once every second day, and once every three days, then once every second day...
so she knows that u still care about her. I myself, as a girl, when i get mad, i secretly wants to be cared, i still wants his attention. and when i dont, i have negative thoughts that he might not like me anymore. and i start getting even more mad, and start losing my feelings. so i strongly advice u should show her that u still there for her, but dont come too strong. just short message like "dont forget to eat", or "hey i found a new song called such and such, i think u should listen to them, they are really nice" stop. dont send her messages that asking her anything, or required any reply, cos she might get "disturbed"
when there is no more words left to say. when tears have no more meaning, what would u do?
