At 26, is there a possibilities that most of her friends are still not married? If that's the case, it's quite normal.
My wife and I dated 10 years and after 1 by 1 her friend got married then only push for me to go ahead.

At 9 years - still need to propose?
2nd thing, u are staying with her family home - are u ready to get marry? To be honest, if financially u guys are still struggling, better plan ahead.
Once kids come into the picture, it's a whole set of different scenario.
