<human>: Okay, well I dunno to begin really, but here we go..

Me and my girlfriend (17f) have been dating since December of 2013, were wanting to make things last, but	 Im honestly a little confused..

So here are a few questions:

What makes for a good long lasting relationship?

We communicate a lot with each other, tell each other what we like when we do somthing, who were with, all around we dont keep secrets, is this a good thing, or could it lead to a downfall?

My best course of jobs/career in th future is finish my vo tech, and get my airplane mechanics license and my pilots, and go though the military, but she doesnt see fit. How do I convince her this is the best? she doesnt want me in military at all..

sorry for all the questions, I just dont know what to do, and her family situation isnt the best so its making things harder on both..

If you can help out, I'd sure appreciate that.

Can you condense the text into three sentences or less?
<bot>: confused on our relationship, and trying to talk my gf that military is my best route just dont know how to address it so she sees it..
