<human>: So my girlfriend and I have been together for going on two years, were very happy together and love each other. She graduated with a degree in dental hygiene for assisting (I think that's how its pronounced) but recently she said she wants to go back to school to be a full blown hygienist. 
Now I'm all for education, I truly am but this whole process will push our lives back easily 4 years. I make great money for my age and would like to do some traveling (to other countries) and she does too, however at the office she works in she only works 2.5 days a week and struggles financially, she gets paid awesome hourly but those short weeks hurt her. She says if she goes back to school she'll come out and easily make $25 an hour.
I'm not trying to be controlling and say no school for you but if she goes to school she'll probably stay at the office she's at and get the same money, same hours which means she'll continue to struggle. I do help out where I can but I try not to "throw" her money because I don't want her to start thinking she can just have it whenever.

Can you give me the gist of the text in a nutshell?
<bot>: girlfriend wants to go back to school and I want to travel, live life while we can. I don't want to be controlling and say no.. Need some advice.
