Heartbroken help!!

Okay so to get right into it, I don’t have any kind of social media but my girlfriend does. And I thought today I would do alittle researching on her account for some fun. We’ve been together for alittle over 10 months, I believe. And shes told me that in her insta bio she’s said she taken and all that fun stuff. But getting to the point is that when I looked up her account, her bio says single.. I’m so heartbroken, i trusted her that she would put taken or some sh*t in her bio but no.

What would you guys do in this situation?Should I talk to her about it? How do I bring it up?!😕
