My (26M) girlfriend (24F) confessed that about a year ago that she told her close friend that if she wasn’t with me currently, she would try something with another guy, should it hurt this much?

As the title implies, my girlfriend told me this about a week ago, I was noticing weird behaviors from her but she always assured that she was fine and it was just work that was making her tired. She was feeling bad, couldn’t sleep and had to finally tell me because it was eating her alive.

After hearing that my world stopped, we have been together for 4 years already and we were always truthful to each other and we hid nothing, that was our commitment, to never hide anything and if something is bothering to just open up and talk about it. I just never expected that it would be like that..

I didn’t know what to think or what to say, all it made me feel is unwanted, and not good enough. She cried and apologized for saying something like that, she doesn’t know what came to her mind to say something like that to her friend. She was ready to accept if I decided to not continue the relationship. I decided that I want to keep going because I do love her with all my heart. But lately I’ve been feeling hurt and sad and I can’t seem to be as I was with her, I’m usually doubting what she tells me now. She wants to make up for what she said and will keep trying to make things go back to how they were, but I can’t get this out of my head.

I don’t know what to do, I’m thinking of trying to let time take its effect and I’ll end up forgetting it, but it’s hard.
