<human>: Can you succinctly summarize the text in 1-3 sentences?

Bear with me here fellows, it's a bit of a read.

We've been together for four months, and we're madly in loaf. 

I need some help deciding what I'm supposed to do. 

She came out of an unsavory relationship and a number of equally unsavory habits. She had very little self-respect and had a very negative self image. Long story short, I became a part of my life and she became a massive part of mine, and we stuck together. 

She's moving 4 hours away to College to study Mechanical Engineering, and I'm super excited for her, she's bright and beautiful and funny and she's going to make loads of friends. 

My question is: What should I do?

I've been losing sleep for days about this. 

I can't bear the thought of being ***that*** boyfriend that stays at home and keeps her from having fun or going out and enjoying herself and the college experience. On the other hand, I'm terrified that she's going to relapse into those really unsavory destructive things that she used to engage in. I'm so so so scared of her losing her focus or drive to succeed in her degree and her studies. 

She's a brilliant person with a caring and loving family that supports her in everything she does, but they don't know that (formerly) unsavory side of her.

She wants to keep our relationship intact, and interact long-distance via Skype/texting/phone calls and the occasional weekend visit. 

I don't want to ruin her experience by being an anchor, holding her back or degrading her experience. I don't want to see her throw away her hard work (or her parent's tuition money). 

What should I do/ask/say/think? I love this girl with all my heart and I don't want to ruin her life or our relationship.
