Can friendship over the internet sustain for years together

yeah why not? if it is a genuine friendship,then it would last for sure! but the only problem is that people over the internet cannot generally be trusted... i knwo this for sure as i have been betrayed by lots of people online.. but when u do meet someone as true as u are then u have one of the most beautiful freindships in this world!

ya but depend to the couple some long time in relationship can be success but some time one of part of the couple break the realtionship and married with another opposite gender.

Yes, they can be lasting. I have three friends I "met" over the internet ten years ago, one I have met in person several times and another I will meet in a couple of months. I have another good friendship of eight years. I do consider these people true friends, and love them dearly.

Friendship is friendship, is friendship. In fact, I would say that friends made over the internet last longer than if they were made in real life. Why? Simply because there are less opportunities to bicker and fight. :P Friends are made on the internet primarily because of similarity in interest - so when you are sharing that common interest, you will talk and laugh and that friendship will remain strong. I do have quite a few "internet friends" whom I still contact from time to time. ;-)
