Heck yeah. It's been 9 years since I came out of undergrad and probably about 5 years since I started thinking about FI. Time seems to go by more quickly with each passing year, and according to my father that will continue! A message board about "retirement" is pretty much the only place left where I think I can reasonably fit into the "young" category of anything anymore!
I can't do anything about the perception of time passing, but I can do something about the "stuff" I accumulate in my life.
I'm 31 and I've got a wife, but no big house (we have a very small house), no late model cars (we're driving one 10 year old Toyota), and no kids yet (although it won't be long). So you can go down the marriage road without picking up all those things right away!
Being on the same page as your spouse about FI is super critical in my opinion. It takes determination to go against the grain of the high spending and high consumption lifestyles all around us, and I can't imagine doing it if my wife wasn't on board - it'd be hard to avoid the slippery slope if my spouse was pulling me downhill!
We don't hesitate to spend on things we value though. We love to travel we've done a few off-the-wall things that are important to us, like buying a small old house in Portugal (where my wife is from) and working on fixing it up over the years - we plan to live there when we hit FIRE. Having that physical reminder of dreams that took shape years ago has helped keep us grounded and focused, and avoid the slippery slope of consumption.
Glad to hear things are going well for you - keep saving, keep your dreams alive (whatever they may be) and be open-minded about adding a few new dreams in there. And see if you can make your upcoming marriage, among other things, a partnership toward FIRE rather than an obstacle to it.
