The Situation with My Girlfriend
I don’t really know where to begin, but my girlfriend of two years and I might be breaking up in two days.
It all started two days ago when she went out to a party. It was mostly just her girlfriends, plus a few guys who were just the boyfriends of the girls there—nothing special, just a normal party. She was drinking and got pretty drunk. Later on, they moved to a different party at some guy’s house. I don’t know exactly what happened there, but there were more guys at this house who were single and probably looking to hook up. I stayed at home. For context, she is 17 and I am 16. Where we live, it’s pretty normal to go out partying, but I’ve never liked it and I never encourage her to go, though she still does it sometimes.
The real issue started because a video surfaced of her leaving that party with a guy I know. They were walking down the street, completely alone, and he had his arm around her waist. When I confronted her with the video, she claimed they were just walking to another party and that everyone else was supposed to join them, but nobody did. So, she said they just decided to turn back. She also claimed she was about to fall, and that’s why the guy grabbed her waist—to keep her from tripping. Since she was very drunk, I suppose that *could* be true, but it is incredibly hard to believe.
The next day, I tried to talk to her about it. Her response was to call me controlling. She told me I never let her do what she wants and that I’m always interrogating her about where she is, who she’s with, and what she's doing. I can understand how that can be frustrating for her, and how having a boyfriend at home constantly asking questions can feel suffocating. But to me, knowing where your partner is and who they are with when they are out drunk with other guys feels like a bare minimum standard for a relationship.
When I tried to explain my side, she completely shut down. She accused me of manipulating her, said I don't trust her, and said she can't be with someone who doesn't trust her. By the end of the day, she just said she needed to be alone to process her emotions and didn't want to talk anymore.
Today, we started talking again. I panicked and sent her a massive text message apologizing for everything. I told her I was probably overreacting because I’m terrified of losing her. I said it was okay if she didn't reply to all my texts and that I should trust her more, since she is my only source of truth. Even though I said all that, I still have my doubts deep down. I don't necessarily think she physically cheated, but I'm worried she might have caught feelings for someone else.
After I sent that long text, she replied saying she has too many conflicting emotions and can't handle discussing this over the phone. She asked if we could meet and talk in person in two days. I agreed, but asked her one direct question: *"Do you want to break up with me?"*
She replied, *"I can't answer that right now. I have too many emotions and I don't want to make a decision I'm not sure about."*
Now, I am completely stressed out. I’m terrified of losing her. At the same time, I know that if she actually caught feelings for another guy, she should leave, because that’s not a healthy relationship for me to be in. But I still don't want to lose her. We've been together for two years, and she is the best girl I've ever been with.
This would be my first massive heartbreak. I’ve had relationships that lasted a few months, but this is two years. This is the person I lost my virginity to, the person I drove my first car with, and the person who has been there for so many of my milestones. It feels terrible that I might lose her over something like this. I don't even know where to turn, so I am just looking for some advice on what to do.
