Wife (F40) cheated on me (M40) with the neighbour and wants to stay in our marital home and maintain the facade of a happy marriage. Should I let her?

I'll be direct. After a year of doing absolutely nothing, I hired a PI who found evidence of my wife having an affair with our neighbour. Our children are grown and don't live with us anymore. Other than fond memories, the marriage is dead. <br><br>Here's the catch. My wife wants us to stay in that house, in the same rooms, and keep pretending we're married. My wife wants to stay because it's "too much hassle" to move and we've lived there for 30 years and so on. She offered to buy me out but she's not in a great financial state. <br><br>In hindsight, I should have moved out after she cheated. But I stayed, thinking it would help our kids cope. Now she's saying I can't change our lives just because of her "indiscretion". <br><br>I'm considering moving elsewhere in the city. It's not the best area. But I'm on a tight budget. I want to stay close to my kids but my wife is saying I'm trying to "punish" her for her "mistake". That she'll be stuck here alone. <br><br>I've heard of people staying in unhappy marriages but continuing to pretend. I asked my therapist if I should stay. Essentially, if I move, my wife will inevitably move in with her lover, so I'd be "enabling" the affair. I should "stay the course" and not let the cheating win. <br><br>I know some of you will yell at me for not divorcing her but I don't want to. It's my fault I didn't leave sooner. I'd rather stay than try to fight for half of the house, which I'd probably lose. I don't care about her sex life but I don't want her sharing our marital bed with her lover. <br><br>Can anyone give me an advice on this?<br><br>&#x200B;<br><br>EDIT: We aren't married anymore. Haven't been for a week. <br><br>I printed the evidence the day before yesterday and gave it to her. I told her I was leaving the house. She freaked out. <br><br>In the end, she left. She went to her lover's. <br><br>I had a realtor over today. She was horrified. She said she'd never seen a house in such bad condition. I'm doing light cleaning over the weekend. <br><br>The kids will be here Monday and my son will help me get the place in better condition. We'll both stay here while the house is sold. We'll spend most of our time with my daughter. <br><br>After the sale, my son and I are buying a new house together. Fortunately, it's not a large place. We can carry it ourselves. We'll have an open house at the end of the month. Hopefully it will sell quickly. We'd like to be out of here by the end of the year. <br><br>I'm working with a lawyer to ensure I get the best settlement. I have a feeling this will get nasty. <br><br>I've been reading a lot of your comments. Thank you for the support and the advice. It's good to know I have so many people looking out for me. <br><br>&#x200B;<br><br>EDIT 2: She wants us to reunite.<br><br>She wants us to reconcile. She'd like me to accept her lover as a part of our relationship. They'd like to live in the house with me. She's offering me compensation. One million dollars. <br><br>I asked her about poly relationships. She admitted she and her lover aren't poly. However, he's willing to share her with me if it means we can continue our marriage. <br><br>In the past, I'd have jumped at this offer. But it feels wrong now. <br><br>&#x200B;<br><br>EDIT 3: It's over.<br><br>I thought about it. I realized my wife was the only reason I didn't end the marriage. Now I have a way out. I don't have to worry about money or staying close to my children. I can start a new life. <br><br>I'm not going to take her money. I'm not going to accept her lover into my home. In exchange, she's not contesting the divorce. <br><br>I've been thinking about our marriage. It's been over for years. I feel like I'm waking up. She's not the woman I married. I'm not the man she married. I don't know why I stayed. <br><br>In a way, I'm glad this happened. I was starting to feel like a part of me was dead. Now I'm free. I have a chance to start anew. <br><br>Thank you to everyone who commented. You've been a great help.
