<human>: My girlfriend and I, both of us are 20, have been together for nearly three years. We started dating before senior year of high school, moved away to college together with some friends, and had a generally smooth relationship up until January. We went through a little bit of trouble, which became extremely exaggerated when my best friend, and one who moved to the college town with us, confessed to her that he's loved her throughout our relationship. She reciprocated the sentiments and I was at a low point of my life, ashamed for sneakily looking at Facebook messages, and especially seeing the two people closest to me conspiring to leave me to be together. Calling her phone repeatedly, without answer, while I knew that they were together at her apartment that night was awful.

We argued a lot and eventually decided to work it out. She never touched him or anything like that. They had one face-to-face conversation, and it involved her telling him that she really wanted to be with me. I understand that stress makes people do stupid things, and I have been trying to forgive her. 

Last night, she went to a party. I don't suspect her of cheating on me at all, as I do mostly trust her. But she has a habit of not paying attention to her phone. That bothers me. I've told her that I would appreciate a text back every once in a while when she's out, and a lot of that is just me being worried about her at a party. She got mad at me for not trusting her, and doesn't seem like she wants to deal with the consequences of what happened in January. Plus, she's telling me that it was a long time ago, and it shouldn't really be an issue anymore. 

I don't **completely** trust her. I've been hoping that it would come back over the last few months, and it mostly has, but there's still a void. For the past few weeks, the relationship has been great again. But, reasonably in my opinion, the love triangle thing fucked with me and the effects are still present. I don't know what the best course of action is. I love her. She loves me. But I don't completely trust her, and she seems like she's running out of patience.

Any advice would be appreciated.

Give me the gist of the text in a nutshell
<bot>: Best friend got in the middle of relationship, and trust is still an issue with the girlfriend. She's growing impatient and doesn't want to face the effects of what happened.
