We got married during my Master's - I don't recommend planning a wedding whilst writing up a dissertation LOL
I know what you mean about the attitude of some other academics; they act like it is a big sordid joke and that it is acceptable to make fun of your relationship. I try not to take it too seriously, but if someone questions your academic ability or the strength of your marriage then it sometimes get upsetting.
The other thing that annoys me is that the academic who had the biggest problem with us actually married a PhD student in one of his former departments - hypocrit! There is another couple (lecturer and PhD student) and no one bats an eyelid. I hate the way it is OK to sleep with a PhD student, but a relationship with an undergraduate (who could easily be the same age as a PhD student) is unacceptable and pervy
