If you realy want to finish it then face to face is the best way. It takes guts and it's a very long process but in the end everyone is better for it. However it does not awlways happen that way. Only split up with one person over the internet and it sucked. Big time. X-( And what's worst is there is no 'break up, no hard feelings' huggles. Just "Well i have to go now, night xx" Nah too good. Face to face is hard, but you'd feel better after.
