My gf (24f) and I (25m) have been together for 6 years, recently she suggested that we open up our relationship because she wants the excitement of guys flirting with her again.

When she initially brought the subject up two weeks ago I told her that I wasn't comfortable with the idea which she responded with "I still love you and want to be with you but if you don't want this then we should break up."

We talked about it some more and when I asked her that if it was just going to be flirting or if she was planning on sleeping with anyone she said that if it happens it happens. After hours of trying to figure things out I reluctantly agreed because I didn't want to lose her as I planned on proposing on our anniversary in February. I found out later the same night, after she told me, that she has had two dating apps on her phone for a couple weeks already and that she's already been "talking" to guys. I told her again that I wasn't comfortable with the whole thing and I especially wasn't ok with her sleeping with other guys.

Last night I asked if she wanted to fool around as our intimate life has been basically non-existent for the past month (not for a lack of trying on my part it's just that's she's never in the mood or tired) and was met with a very enthusiastic "sure!" followed by " after that I'm going to go see a friend." I was immediately turned off because I knew she meant another guy and I started getting ready to go to sleep as I worked early in the morning. She proceeded to get ready and left at 11pm. It's now 5am and I'm leaving for work and she just got home and went straight to the washroom.

I'm not sure what to do anymore.

Edit: Thank you to everyone who gave helpful advice, I'm still reading through everything and more keep coming. I feel like I should clarify some things.

Yes, I agreed to open our relationship against better judgement because I didn't want to lose her. That meant I was able to see other people too but I choose not to because I only wanted to be with her and I made that clear to her.

Despite the facts that she's had dating apps for awhile and spent time (a few hours here and there, last night was the longest) at a guy's house, she insists that nothing happened and that they're just friends who flirt with eachother... that's it.

Edit 2: Forgot to add - STD's aren't a worry, for me anyways, we both got tested last month as regular checkups and were both clear and we haven't done anything since.
