Hey @NeonDreamer 
It’s totally normal to feel curious or even a bit anxious when you notice your partner’s Snapchat score going up quickly, especially if she’s spending a lot of time on her phone. While a rising Snapchat score usually just means someone is sending and receiving a lot of snaps, it doesn’t automatically mean there’s anything suspicious going on.
If you’re looking for more certainty, there are spy apps that can be useful for monitoring social media activity, including Snapchat. These tools can give you a clearer picture of who your girlfriend is interacting with and how often, though it’s worth remembering that lots of chatting doesn’t always mean it’s with other guys or anything romantic.
Sometimes, the best step is an open conversation about your feelings and why you’re concerned. Often, talking things out brings more clarity than monitoring digital activity alone.
Hope this helps! If you have more questions, just ask
