She Keep Saying "Meal Ticket"

I started dating this girl awhile back and when we first started dating it was great. We were close friends before, so we had a good base relationship set up and then we started dating and things moved quickly.

Fast forward and we've talked about big plans together (marriage, kids, where to live, etc). At first it didn't scare me, which was something in the past would scare the shit out of me so I figured this girl must be special.

But recently it stopped being about "our" future, but rather "my" future. I am currently in law school and working hard to get a commission in the JAG Corps after college. She's very supportive, but almost to the point of scary supportive.

Recently she says things like "when you're in the military, I'll have all my pregnancies paid for by their healthcare", or "you'll have such a good pension when you retire", or "with your rank and position we'll be able to have a beautiful house", and most recently "if you want me to go to all these fancy events with you, I'm gonna need new clothes, which I'm gonna buy with your credit card".

Meanwhile, she has no goals, works a couple part time jobs as a nanny and a personal assistant, and generally no direction in life. On top of it all, she's let herself go physically and has put on weight and refuses to go to the gym. I brought this up to her how it seems she's lost fire to do anything and her response was "But baby, my dreams are your dreams. So I'm focusing all my energy to help you achieve your dreams".

Now I've read on here how our society lacks women who only want to be good mothers and good wives to their husbands, but I'm wondering if she is teetering between being super supportive of her man and future family, or she sees the benefits and is latching on.

The last thing I would want to do is get too serious with someone who is only using me as a meal ticket. I would like someone with a little fire who contributes to the relationship rather than hoping I achieve everything.

UPDATE: So first off thank you for all the comments and feedback. Didn't expect it to get this much traction. But here's the update. First I took many of your guys' advice and started playing some dread game with her. Pushed on things that pissed me off and how I hated it. Also, she knows I'm tutoring this HB (Paraguayan chick with a tight body) and I like to drop her into conversation every now and then "Oh Noelia said the funniest thing today" or "Noelia and I both love to workout, she's a real gym rat like me".

All of sudden, complete change in attitude. Now it's "Whatever you want honey", "What can I do to make your day easier?", "How do you want to fuck me tonight?". She's backed off the whole JAG thing and said whatever I want to do she supports, JAG or no JAG. She's enrolling back in school for spring semester to get her pre-reqs done for Master's program.

Finally and most importantly, she's hitting the gym again and has asked me to help her learn how to lift. This one was a simply throwing down the gauntlet. After I ran 3 miles in a Marine Bootcamp obstacle run, I told her how hard it was but rewarding, and basically said "Fitness is important to me, so it should be important to you too".

Now she's completely about making me happy in any way possible, doing whatever it takes to keep me around (even though I'm still spinning that tutor girl). Bottom line, I think she knows now, if you want to keep me, you better keep up with me.

Thanks Red Pill!
