Girlfriend in another college?

So me and my girlfriend are both 18 years old, freshmen in college.

We're in a long-distance relationship, and we have been ever since we've first started going out, which is a little less than a year ago. I'm from San Diego, she's from LA. She goes to college in Santa Barbara now which is about twice the distance, and I'm going to a community college a few miles from my house.

Even though I hate to admit it, I'm a little bit of the jealous type. Since I'm not there to be with her everyday, I feel uncomfortable when she talks and hangs out with guys that I don't know. Now that she's in college, I feel more out of control since there's a lot of horny college guys and my girlfriend told me that she wants to go out to party since she doesn't want to be the girl who stays home all the time. I'm highly uncomfortable about it, but she just tells me I'm overreacting. I'm learning to just go with it, and just trying to be the best boyfriend so that she can see that she'd be losing out if she decided to cheat.

But, with her in a university, she's meeting new friends, and basically has an entire new life. I can only see her through webcamming, but she's hardly home to talk to. I feel like I'm slowly being pushed out in a way. Before college, we would webcam every moment we got, but now she has new friends, she's on her own without her parents watching over, so she always goes out, and the change is so sudden that I feel like I don't play a part in this "new" life of hers.

I'm going to visit her in two weeks, so I that I can try to meet her friends, learn her new environment so that I can kinda squeeze myself back into her world.

I know, I should let her explore since she's in college, and I want to, but I don't have anybody to really talk to now that she's so busy. I go to school in the morning, then work all day until night. The friends that I do have only know how to drink alcohol and smoke weed, and I grew out of that phase a long time ago. So I'm starting to feel alone, I don't want to lose her, but I don't want to suffocate her at the same time.

I just want to feel like I still play a part in her life, and I want her to miss me, to show me that she still wants me. I probably give her too much of me, and so I decided to take a break.

Just a little white lie, and it's the only lie I've ever done in the relationship, but I told her that my phone and internet is disconnected for the next week or so. I'm just trying to see how she reacts without me in her life, and at the same time I'm trying to discover myself without her as well. I still love her, I'm not trying to break up with her or anything like that.

So it's not really a question, but I just wanted to get some perspective from other people. Sorry if it's too long!
