IR NPR. My (28M) girlfriend (33F) was using her dating app the whole time behind my back.

I think there's a red flag in here somewhere. I'll try to make this as short as possible because I'm not sure exactly what to share. My girlfriend has a child from a previous relationship, and I live with them.<br><br>*TL/DR at the bottom.*<br><br>I have lived with my girlfriend of 20 months since May 2023. We were planning on leaving the state together but it's not happening. Despite my apartment search, I still live on her couch. She's recently started dating again behind my back. Even when I said I'm moving out, she said that it's too soon.<br><br>Just to clarify. I am still living at her house, and will be for a while. There is no plan in place, although I want to leave. She is my roommate that I am dating. I don't have a hard deadline for moving out, and she has agreed to not move in with me.<br><br>I (28M) live with my girlfriend (33F) and her daughter (10F), and we've been in a relationship for a little over 1.5 years. The relationship has been really amazing, and she has been a great partner. The problem in our relationship is that she wants to stay in this town, and I want to leave. When I asked her to move out of state with me, she rejected, so I'm starting to make plans to move in the next 6 to 12 months. She knows this, and has even acknowledged that I will be moving. Everything was wonderful in the relationship until the other day, when I discovered she was using her dating app, despite knowing that we were making plans to leave. I confronted her about it, and she got mad at me, saying I shouldn't have done that. I don't know how to approach this situation.<br><br>The other day, I was at home with her daughter, and I borrowed her tablet to look YouTube Kids for a movie and accidentally clicked on Bumble. I knew she had a dating app, and I'm on it too. Nothing wrong with that.<br><br>To my surprise, she had apparently been using it actively. I know it was her, because her profile picture is a picture of her. She also has a pretty rare first name (think Elara or something).<br><br>I confronted her about it, and showed her the evidence. She freaked out. Even when I tried to explain that it was an accident, she was mad at me. She said that she was just messing around and I shouldn't have done that. I also offered to delete the screenshots. She agreed.<br><br>Even with the screenshots deleted, she is mad at me. She is not talking to me. I don't understand what's going on. I don't understand why she wants to date other people behind my back when we both know I'll be moving. Is this a red flag? Am I overreacting? How do I approach this situation?<br><br>&#x200B;<br><br>I think there's a red flag in here somewhere, but I'm not sure what it is.<br><br>&#x200B;<br><br>**TL/DR:** My girlfriend was using her dating app. She knows I'll be moving over the next 12 months, and I confronted her. Everything was great until then.
