Regardless, one of my best friend started dating her 2 years ago. We don't live in the same city anymore, so I don't see him as much and he hid the fact that he was dating her from me.
He announced it to me a few weeks ago. Today, I received an apology from my ex for her cheating. She told me she was in complete denial about what she had done to me, that she was a teenager at the time, bla bla bla (classical excuses). Anyways, an apology is an apology. My ex also announced me that they're thinking of getting married and that she doesn't want to be the reason why my friend and I part ways.
I don't really know what to do. To be honest, I am still very bitter at my ex for everything that happened, despite the (LATE) apology. On the other hand, it's been years since that happened. I don't wanna loose my friend over this and I cannot stay angry at her my entire life.
What do you think I should do?
