<human>: Can you give me a shortened version of the text?

I'm a female (21), and the person in question is male (22). 

Relevant data: We go to school together; he's a senior, I'm a junior, we work together on campus. We've known each other for about a year and a half, and he started expressing interest in being more than friends around New Year's. Since around February, we'e been hooking up on a fairly consistent basis, went out to dinner a couple times, and spend a lot of extra time at work together, just hanging out.

The problem is that I feel like I get completely mixed signals from him depending on the day. Sometimes he'll one word text me and we'll essentially be out of touch for a day, other times we talk for hours and cuddle during movies. The sex is fantastic, but then sometimes he'll go ahead and call it "making love" or make a joke about how I'll be "dating a homeless guy in six months" when he doesn't get into grad school.

As for me, I'm totally game to continue with hooking up and being friends or to have it mature into something more substantial. I just despise the liminal space between these two options and want to know what others feel he's leaning towards. 

I know it's not much info, but I'm glad to provide more if it'll help. Just looking for a few second opinions is all.
<bot>: Guy I've been hooking up with sends mixed signals and I cannot figure out whether he's looking for something serious or just wants to be laid back about this.
