hello there benson.i have almost the same experience with you.having an online relationship and living long distance.but what seperate us is that i was really glad that i got to meet her in person when i got back home(i'm studying oversea and she's at my home country).we do spend a lot of time e-mailing and talking to each other and even it cost me a lot that time it just don't matter(we can't use skype).it's true that i also did confess to her on the phone,it's really take courage.as for you benson,it's unlucky that you didn't have chance to confess to her.i was thinking that maybe she has waited for you to confess long enough or maybe she just met someone in real life and they started dating.i know that the truth is painful,but there must be reason for her to left you just like that.there is no certainty in online relationship,the thing you need the most is trust.looking at your condition now,it's been really long since you last contacted her.there is possibly chance that she might contact you back,but if it is 4 months already,i think it's to long enough.all that i could say,move on benson-san,there is more waiting for good guy like you.yes,it's a miracle that she will contact you back.but waiting long enough for nothing is not really worth it!!
