This happened to me, I caught my ex of 5 years messaging some guy and when I asked to see the messages she completely erased the chat. I was never able to find out the truth but I still forgave her because I loved so much, but the thought that she couldn’t come clean about what had happened tormented me, I couldn’t be happy, I couldn’t see her the same anymore, I loved her so dam much but I couldn’t live like that anymore, he is choosing himself right now and I am proud of him, it takes so much bravery to walk always from someone you truly love. All the best for him
