I tracked my girlfriend's location while shopping for our wedding rings

I feel like I'm in a really weird position. My girlfriend is going to get a ring that we've decided on together. I've been trying to afford it for a while. I have a lot of anxiety and I feel like the pressure to make it happen is killing me. I decided to track her phone while I was out shopping for rings to see where she was. I was expecting to see that she was at the park. That's where she's usually been when I see her on maps. I tracked her and she was at a guy's house about an hour and I half away. I looked up that location and found that's where my future brother-in-law lives.<br><br>I'm really concerned. I texted her to find out what was going on and she said it was what-the-hell-ever, and that she was just getting a ride from him to some stuff. I get that. I asked whether I was the man for her and she said that yes I am and she would be with me forever. I'm really nervous. I don't know what to do. I feel like I'm being cheated on. I don't want to hear that it's fine when I don't think it is.<br><br>I just don't feel like I'm good enough for her. She's used to dating guys that are more verbally abusive and emotionally unavailable, and I'm just trying to do everything I can to make her happy. Can you give me some advice on whether I should confront her about this? Please.
