So my advice to you would be this - care more about your development as person than the development of your penis.
Women do not make men happy and vice versa. Instead, we learn to find satisfaction in ourselves and our “right action.”
If you have this philosophy, her cheating on you is simply a fact that comes and then goes. Why? Because you never depended on her for “happiness” in the first place. Now that you know her character, I argue it should be a weight off of your shoulders. You’re now free to continue your life’s journey unfettered by a liar.
Context: I still don’t have hard proof that an ex that was important to me cheated. I spoke to other girls in a sexual way... but when confronted, I was honest with her about it and why I was doing it - there were problems in our relationship. I thus learned to always confront my issues headon because, if I don’t, I’ll be tempted to tarnish my own character. Better to break a relationship that probably wasn’t going to satisfy me in the long run that to tarnish my own character. Lesson learned.
She probably revenge cheated. She never came clean about it, but all the clues were there. Maybe that’s the way it needed to be in her mind for her to regain her self respect. ... Can i really be that angry that I hurt her badly enough that she tarnished her own character to try to repair an unfixable hole in her mind?
Should we get upset when people hurt themselves to “relieve the pain”?
When we have introspection about our own flaws and character and tolerance for the humanity of others, then these acts that seem so devastating seem strangely natural.
I no longer feel much about it except sadness. Sadness at my own character flaws. Sadness at her character flaws. Acceptance that we were both in pain. Forgiveness for whatever she did to herself and to me.
And determination to be a better person for my own sake.
I think you should use this experience to become a better person.
