Fiancé won’t help me with my college dreams by moving and doesn’t put in the effort to try. We have a new child together now and I have 2 months to leave, what do I do?

Hi, so I met my fiancé 2 years ago, she’s really sweet and has a 11 year old son. I was already planning on going to school for a computer science career but didn’t get into the process of going until a couple months after we started dating. Ended up doing a couple semesters of community college and taking a break when we started running into financial troubles. I always intended to go back to school when I had the chance and she knew this. We ended up having a son last September. October rolls around I got the opportunity to attend the university of my dreams with almost no student debt with the caveat that I would have to provide my own living expenses and she got excited with me. I was placed in a flex program where I start classes online had 6 months to move to the schools location and start on campus. I picked up more hours at work so I have been working around 35-40 hours a week along with excelling in my classes with straight A’s (my school workload is about 20 hours a week). Over time she’s been putting less effort into earning to save for the move and been increasingly worried that we won’t make it out that and I’ve tried to insure her that we can if we put in the extra effort up front. I was the say we are also currently living with her parents while we are “saving”. Now with a new child she wasn’t able to work for the first 6-8 weeks after he was born and I did my best to help the best I could and still try to do what I can between work and school. She put in a lot of work December for Christmas and was making good money (spark delivery driver). Come this month and she’s earned only 30 bucks the entire month with the decrease in effort. Any time I bring it up she gets mad and gives me the “oh well guess you can’t go to school”, and we’ve been arguing more frequently to the point it can get a little ugly with words sometimes. I’ve been trying my best, I work 40 hours as an overnight stocker at Walmart (so I can transfer to the location near school), school for 20+ hours, and get my son when I can so she can have her breaks. I only have 2 months left before I have to leave and don’t wanna lose the scholarship I get for going on campus. Not only is it my dream school but also dream career and I already have student loans out for the credits that transferred over from community college as well as the little I needed for the bachelors program. I don’t wanna give up on this dream and I love my son so I don’t really wanna leave him. If I give it up, lose the scholarship and the chance to go to the school of my dreams I may end up resenting her, and there my 4 months left before old to think of too. Im 28(M) and she’s 26(F) btw. I feel like I’m between a rock and a hard place rn. What do I do?
