In her first year of college, she cheated on me twice.
First, she met this guy with a group of friends, she admits that she was being flirtatious, he asked her to speak alone, to which she agreed and they kissed in the parking lot.
Later in that year she had a month long flirtatious fling with another man, which she says she ended.
This all happened in 2016, and she broke up with me at the end of that year.
At the beginning of 2018 we started speaking again, and I had a conversation with her in which I wanted to bring everything into the light so that we can start clean again.
In high-school she cheated once but I knew about this and we worked things out. I asked her if she cheated again after and she said no.
Recently we had a conversation talking about what we could consider to be unforgivable. She got really nervous and I kept pressing about what made her so nervous, and 2 weeks later she finally admitted to this.
I know it happened a long time ago but I can’t get over the fact that she lied to my face.
She said at the time she was really insecure and wanted validation from someone other than me.
She said she lied about it because she realized I’m the only one she wants and was terrified about what he truth would do to us.
She hasn’t given me a reason to think she has cheated since we got back together but I can’t accept that she would lie to me.
What do I do about this? Is it possible that we can work things out? How do I know if she’s different now? If I forgive her a second time, will she subconsciously lose all respect for me?
