I met a guy at my internship at the beginning of the summer, "Matt." He was funny, smart, cute and extremely outgoing, and I immediately developed a crush. We flirted a little for a few weeks then he finally asked me out. It's been perfect. He's one of the sweetest guys I've ever been with, and if the timing had been better we would've already become exclusive.
The thing is, he's moving four hours away tomorrow for school. He'll be coming back about one weekend a month, but it might become less frequent the longer he stays. I'm in school too, so it'll also be difficult for me to travel there a lot. I haven't had a serious relationship since high school that was pretty awful, and he had one long distance relationship that ended horribly a little over a year ago. So neither of us are too keen on putting that pressure on our newly formed relationship. I just really don't think we have enough of a foundation to enter into an LDR, which can tear apart even the most stable of relationships. So we decided to keep talking casually while he's gone, see what happens and if we're both still single and want the same things during winter break we'll try it out.
Recently though I've been wondering if this is the right decision. I have such real feelings for this guy, the strongest I've felt in a while. And I know he feels the same way. I'll be devastated if he starts seeing another girl. I don't want him to become "the one who got away." 
But how do I know this isn't just the honeymoon period and things will get so much harder when he leaves? We're so young, and I don't know if I want the stress. So I'm torn between giving it a chance with the risk of it failing and us hating each other, or staying single with the risk of him finding someone else and I regret not going for it. 
Have any of you guys been in this situation? What would you do if you were me?
