Don't know what to do

I don't even know where to start with this one..... My grandpa calls my dad and says that my grandma would like to talk to me. Sounds weird so far? (It gets better) So I'm thinking that my grandma wants to go to lunch, so I stall for a day and call her back. My grandpa answers (and can actually hear me! He's 93) Anyway, he tells me that grandma and him wanted to talk to me....so now I'm a little nervous, I don't talk to my grandparents much, we talk at the holiday's and occasional visits throughout the year, but we don't get real personal.
And now my grandma is on the phone too, so she asks me "Abi, do you still want to go to NIU." Now I'm beyond confused....She goes on to explain that my grandma and grandpa have been online doing some research and want to pay for me to go to NIU!
I'm not sure why, but I get the impression my grandma doesn't like that I went to MCC, she's always asking why I didn't go to a four year school. Basically it all comes down to I didn't want to start my life with all that debt. You graduate from college with $50,000+ in student loans then have to get yourself a car and a place to live and I just don't want to start life like that. And when I graduated high school there was this cute guy I couldn't imagine being away from for more than a couple days at at time.
So now the question is what do I do. On the one hand it's great timing, because I'm at this stupid stage where I'm losing the friends I had in high school and need to make new ones...including the before mentioned cute guy. But on the other hand I love where I'm at at work. I just went through personal banker training and I know if I leave they wont hold my job for me. And when I decided I was attending MCC I took classes to get a degree from them, I didn't take classes that would transfer or possibly even apply to a degree that NIU would offer me. Needless to say I don't think I'll be sleeping for a while trying to figre out what to do.
