I learned to ignore the family a long time ago.

At first they didn't agree with my decision to join the military. Then they didn't agree with my choice of wife. Then they didn't think it was a good idea to go back to school at my age (i'll finish in my 40s, not too bad I think). Now they don't agree with my choice of girlfriend.

In short, I stopped worrying about making them happy a long time ago. When I got enough of the questions I simply told them (for pretty much each subject though) that if they kept bringing it up then they could do without me around. Well except with my wife, I plainly said to them that if my wife wasn't good enough for them than they didn't need to see either of us.

It worked for the most part, it seems that they are usually able to keep their opinions to themselves these days.
