I'm hoping this is the right place to post this. I'm looking specifically for advice from women and it involved both relationship questions and questions about life in general.

For general upfront information:

I'm a 32-year-old female. I am halfway through my Associate's degree. I share a home with my 33-year-old boyfriend (let's call him C). He pays all the bills, I have student loans for my education, but he takes care of everything else. We have lived together for almost 3 years. I have been out of work since April of last year with the idea that I would focus full-time on education, but money is becoming tighter and C is having a hard time staying caught up on bills, so I got a part-time job that starts a in couple weeks. I am not taking summer classes so I can help him out financially as well as save up money for myself. I will be starting classes again in the fall, however.

Here's where I need the advice: Should I continue working towards my Associate's degree, then heading to a Bachelor's and Master's, or should I change my career path to something simpler and less time-consuming like becoming a Medical Assistant? The college I attend offers a certificate program for Medical Assisting that would only take 3 semesters to complete. There's always a demand for them, and even though I wouldn't be making great money, it would be decent and I could actually contribute a nice amount towards the household funds. If I went the 'regular' college way, I would be in school for probably the next 6 years. C says he doesn't mind if it takes me that long, as I can work part-time or even full-time after I get my BA.

The other problem I am having is with our relationship. We we first got together, I always assumed we would marry and start a family. Over these last few years, though, C has made it clear that he won't marry me or have children with me. He won't talk about 'our' future. When he mentions things he wants to do, like travel or eventually buy a new house with more land, he always talks about 'him' doing that, and not 'us.' When I have confronted him on it, he usually ignores me/doesn't answer me directly. Only one time has he given me what I thought was an honest answer. He told me, "well, you know things don't last forever. people change." I know it's a vague statement, but I am pretty sure I know that he meant he didn't expect us to stay together. I am mostly sure that, when I complete college at whatever time I complete it, he will ask me to leave.

So what do I do, 2xC? Get out of college faster and hopefully make enough money to support myself, or take the long route, eventually making a good amount of money, but being sad in the meantime, knowing he's going to dump me?

TL;DR Do I stay in school a long time or a short time knowing my boyfriend is going to break up with me when I am finished?

I know I'm not happy with him, but I still love him and am in love with him. Both school and being in a stable, loving relationship are important to me.

Edit: One thing I forgot to say is I would want to try to continue my education after I became a Med Assist, but it would be a long, expensive road. But do I really want to be just finishing up a degree in my 40s?
