I really don't know, I do see both sides but I feel I can relate more to her point of view. I suppose timings do make a difference as well. Originally the plan was to go to hers so it went from going to her to now she has to travel hours, which is unexpected time and expenses. And although she doesn't have children that is still a very long way! For anyone to go, and by herself, I would still be concerned about safety. I live in London and if someone said they were coming to visit, but then said actually can I come to meet them in Birmingham, as much as they are in the same country I would still consider that person unrealisticly far away and in an area I'm not familiar with either.
But how long was this meeting planned? Well in advance or just recently or quite short notice? And when did the plan change? Either way you both tried to get together but couldn't this time, hopefully there will be another time with better planning
