<human>: Can you summarize the given text in a few sentences?

So my girlfriend wants to attain her Master's  in Public Health. 
But, 
1. She doesn't know what job opportunities it can open.
2. I think she only does it because of  the PERCEIVED(key word) educational gap between us.
3. She relies way too much help from me in her undergraduate classes. 

If I bring these up, she thinks its because I don't support her. I do, that's why I help her with her HW all the time. When I asked her in details about why she wants to go into the program, it just seems that she wants to do it because I am in a PhD program and she thinks she's not educated enough for me. I told her not to think about it and I love her regardless. She also need a lot of help with HW and struggles in her classes without my assistance. 

At this point I think a MPH is way too difficult for her and I can't carry her through the program while I am working towards my education. 

How should I handle it? 

Do i let her apply? I don't want her to take on additional loans, especially if the work at the graduate level is too hard for her and she ends up dropping from the program. She struggles in her undergraduate courses without me and I am not sure I have the skills to continue my graduate work and help hers as well if she is in the mph program.  
But, if I advice her not to apply, I think it will crush her and hurt our relationship. 

I love this girl with all my heart, but I don't know how I should go about it.
<bot>: GF wants to go to graduate school, but based on my experience with her is for the wrong reasons and I seriously doubt she can handle it.
