No, no and no! I have already been cheated on and I myself discovered it.... I felt very bad.
I am so sorry you had to go through that. It is really bad place to be in.
And also things will not be like before there will always be that doubt and there is no point in that tension. Better each one on their own way and that's it.
These are my exact sentiments. I have to keep second-guessing whatever you say. A split would just save us all the drama that follows afterwards.
