If you’re open to fixing things, suggest a “trust-rebuilding” period. Recommend doing counseling together—not to assign blame, but to learn how to communicate better and understand each other’s decision-making styles. The house situation can become a lesson in how you both handle disagreements.
Make it clear that counseling is about strengthening the relationship, not punishing anyone. If he’s genuinely willing to work on himself and grow with you, that’s a strong sign the relationship still matters to him.
When you do talk again, focus on shared values instead of rehashing the argument. Ask questions like, “What does partnership mean to you?” and “How should we make big decisions together?” His answers will show whether this was a one-time mistake or a deeper incompatibility.
Share your own vision for the future and see if it aligns with his. A calm conversation about values may show that rebuilding is possible—or reveal that moving on is the healthier choice.
