If your marriage was really “wonderful” for 7 years, why are you willing to accept what you feel is inevitable? Instead of working on hiding your assets, why not see a therapist? a couple’s counselor……….something.
Relationships have an energy to them as does everything else we participate in. Sometimes that energy feels easy and joyful and other times that energy feels very stuck or difficult. That is normal. Most people do not talk about their relationships honestly, so most of us have an idealized or romantic notion of what a relationship should be.
If you still feel love for your wife, then get thee to a marriage counselor and figure this out, no matter what has happened.
I wish you peace and joy on your journey. I wish you the ability to uncover that which has been difficult for you to see and deal with it honestly.
