I was the other woman in my own marriage

TIFU by checking my husband phone and finding out I was the other woman in my own marriage. Let me explain because this is not what you think. My name is Danielle and I have been married to Marcus for four years. We met at a wedding, fell fast, and got married within eight months. Everyone said it was too quick but I did not care. I was in love. Three weeks ago I noticed Marcus started locking his phone with a new passcode. He never did that before. He also started taking calls outside on the porch at odd hours. My gut told me something was wrong. One night he fell asleep early after a few drinks and his phone was sitting on the nightstand unlocked. I should have put it down. I did not. I opened his messages and found a thread with a woman named Priya. The messages went back almost five years. Five years. That is one year before Marcus and I even met. I scrolled through hundreds of messages. They talked every single day. They said good morning and good night to each other like a couple. There were photos of them together at dinners, at a beach, even at what looked like a hotel room. My hands were shaking so hard I almost dropped the phone. Then I found the message that made my stomach drop completely. Priya had written to him saying she could not keep doing this to me, meaning me, Danielle. She said she felt guilty every single day knowing he was married to someone who had no idea. Marcus had replied that he would tell me soon, that he just needed the right time. Soon. After four years of marriage. I sat there in the dark staring at his sleeping face wondering who this man even was. I did not wake him up right away. I spent the next two days quietly digging. I found hotel receipts in an old email account he forgot to log out of on our shared computer. I found a second bank account with deposits that matched gifts sent to Priya based on dates in their messages. The betrayal was not just emotional. It was financial too. He had been pulling money from our joint savings labeled as business expenses. There was no business. When I finally confronted him I laid everything out on the kitchen table, the messages, the receipts, the bank statements. He went pale. He did not even try to deny it at first. He just kept saying my name over and over like that would fix anything. Then he said something that truly shocked me. He said Priya was not just an affair. She was his first wife. They had never actually divorced. He married me while still legally married to her. I felt the floor disappear beneath me. Four years of my life, my marriage, my vows, meant nothing because legally I was never even his wife. He tried to explain that the divorce paperwork got stuck somewhere and he kept meaning to finalize it but things with Priya got complicated again and he could not let her go either. He wanted both of us. He actually said he loved us both differently and thought he could make it work forever without either of us finding out. I packed a bag that same night and stayed with my sister. I contacted a lawyer the next morning. Turns out since the divorce was never finalized, my marriage to Marcus is not even legally valid. I am not his wife. I never was. Priya reached out to me a week later, crying, saying she had no idea about me for the first two years and only recently learned the truth herself. We ended up talking for hours. Strangely enough we are not enemies. We are both victims of the same lie told by the same man. Now Marcus is facing potential fraud charges for the hidden accounts and possibly bigamy depending on what the lawyers decide. He keeps calling me begging me to understand his side. I have nothing left to understand. I gave four years to a marriage that was never real while he lived a double life between two women who trusted him completely. Priya and I still talk sometimes. We joke darkly that we should start a support group. Marcus lost both of us in one single week after years of lying. I keep asking myself how I missed this for so long and whether there were signs I ignored because I loved him too much to look closely. Was I the fool here or just another victim of a master manipulator who almost got away with living two entire lives at once.
