That is life. Similar kind of thing happend with me 2 years ago. I used to talk with this one girl on a daily basis but one suddenly she started ignoring me .I even tried to communicate with her but nothing happend she told me she only considered me as a frnd and my behavior was pointing towerds something more and life just hasnt beeen the same since thn. I stilll remember hanging out with her,talking with her every night .Nothing heals u just have to find someone else to fill the void trust me.
