<human>: Can you summarize the given text in a few sentences?

I've been with my SO for a while, for highschool standards (she's also my first SO), and she's in college right now and I'm in high school. We started dating at the end of her highschool.

 She currently goes to a college that's about a 30 minute drive from my house so I get to visit her about 3 times a week. So things have been going great for the last two months, but our relationship has had a very tough rough patch.

For about a month before she went off to college, she hated being touched by me, she avoided saying "i love you too", and she held doubts on whether we would work in college. She justifies all of this by explaining she felt hormonal from her birth control and stressed because of other events over the summer, but she has apologized for it anyways. The whole ordeal didn't end until I almost broke up with her.

So I always thought I was going to the same college as her, and told her that over the last couple months, but out-of-state colleges are beginning to look very appealing too. So I told her about this, and she asked"do you think it's worth continuing this if you're going out of state?" Also, she does not want to try a long-distance relationship.

So i said, "I don't know, we'll see. I think i'm most likely going to your college." She still seemed unconvinced. My girlfriend is VERY careful with her emotional investment, for she had been in one relationship before where she gave in everything and the guy invested little. It left her broken for a long time. <--All her words

So, now basically, I feel a little pressured and blackmailed because I don't want her to draw up her defenses and retreat emotionally. 

I don't want things to return to like they were in our rough patch, and I hate how she may be able to withdraw from our relationship whenever she wants to. I feel completely insecure and broken. Someone help me out. How do I go about doing this?
<bot>: GF has magical ability to withdraw emotionally from the relationship when she wants to. (read the description, not that long, and my situation will make sense)
