I like this advice.
Some people are better at getting over it than others.
I sucked at getting over it.
My ex cheated on me after the first year, and I stayed with him for 4 years after that.
I never got over it. It continued to fuck with my head for 4 years.
So if you can let it go, then try and work it out.
Be honest with yourself.
If this is going to be too much for you, then just leave.
And about you wanting her to tell you...
You really dont want that.
It wont make things better.
You think you want the details, but the more you know the more it will hurt.
