<human>: Give me a shortened version of the text

We have been dating for just over a year now, and have had a few ups and downs like any relationship, and for part of it were long distance. She [22F] recently avoided pretty much any contact with me [21M] for the last week, including the day of our one year anniversary. 

Today we talked briefly, and she told me that thoughts had been piling up on her as of late, and that essentially, she is not sure if she wants to continue the relationship. 

For clarification, she has been under a great deal of stress lately with college and part of her family moving into her house temporarily. The last week where she did not talk to me was spring break, and I live two hours away.

Some of the reasons she stated to me where some comments I had made, one in regards to the smell of her house (she has many pets, and I had once made a comment saying her house smelled kinda funky), and the other comment was in regards to me saying that I initially didn't want to meet her other part of her family, even though at the time I was basically jealous because I knew that I would have less time to spend with her when they came. It was a crummy thing to say, and I felt bad after saying it, but I'm only human and have my flaws.

We have had a healthy relationship, and have made it work even through our separation during the fall semester, as I was studying abroad in Europe, and the previous summer, where we didn't see each other that much. 

I'm do not want to see this relationship end. I realize I made mistakes, my mouth tends to move faster than my brain. My question is, what can I do? I left her with a message saying I want things to work, and am going to give her space, but beyond that, I just don't know.
<bot>: Girlfriend of just over a year seems to be ready to end it. I'm not. I've made a few mistakes, but I want to fix the relationship. What can I do?
