Its not just men that find this problem with relationships and aviation. I had the long term boyfriend and set off to do my CPL and IR thinking that it would be ok. One year later and visits home every weekend to see him it wasn't working, i dumped him only to have him say that i didn't see him enough and i should be home all the time. You see its a dream to fly and to some people its a very long time to fullfill that dream, you deserve to be selfish sometimes. Not all the time but sometimes. Don't worry about the girlfriends, i find the more you keep them informed, eg. explaining what an ILS is and why its not "just like riding a bike" the more support and understanding you get.
oh yeh query, really inspiring you were a wannabe once and people need support not insults.
