I [33M] want to break up with my GF [33F] of 15 years because I’ve fallen for my daughter [22F]

I can’t tell anyone about this. Not even my closest of friends. I’ve been with my GF pretty much our whole lives. High school sweethearts, we got married young and started having kids soon after. But over the past few years, we grew distant in ways I didn’t even realize until my daughter got older. She moved abroad after high school, so we hadn’t seen her in a while. But when she came back, I noticed something about her that I can’t lie about. I found her incredibly attractive. <br><br>Now, I didn’t see her like that when she was young. I knew something was wrong with me, and I tried to fight it. I read the bible, went to confession, prayed, did everything I could in order to try to be a good father once again. But the more I saw her, the more I fell for her. <br><br>We had sexual conversations, but not too sexual. She’s been a great friend, and she’s always been mature and wise beyond her years. I knew how bad it was, but I couldn’t stop myself. I couldn’t help but feel that she was “the one” for me. I started comparing the two, and that’s when it hit me. I realized I hadn’t loved my wife in a very long time. She always talked like a mom, and never like she used to. I missed the girl I love. My daughter filled that void, and I didn’t know what to do. <br><br>So now, I want to end my marriage. The thought of never seeing my daughter again kills me, but I can’t stay in a marriage where I don’t love my wife. The thought of cheating doesn’t make me feel any better, I’d rather be upfront. I know my daughter will never see me the way I see her, but I’d rather be alone than be with someone I don’t love.<br><br>What should I do?
