Hi everyone, I need some advice!

My gf and I have been dating for 1.5 years and we've brought up getting married and having kids in the future but it seems our timelines are drastically different. And our life paths are heading in different directions

Some background info: she just started nursing school after getting a bachelor's degree so it's another 2.5 years before she graduates. Afterwards she wants to do another 1-2 year master program in a different city

I graduated and have been working for 5 years now so I'm ready to make the next step in my life. Adding up the years of schooling and potentially work experience in between that, my gf might not be ready for having kids till I'm close to 33. 

I just feel like it's a long time to wait for someone. My fear is that if things don't end up working out in the end, I'll have lost a number of years that were spent 'waiting'.
<bot>: gf has several years of undergrad/work/masters left before she wants marriage/kids but I want kids sooner than that
