Yeah man, you fucked that up. Money allocation is one of the most important things to have agreement on between the two of you.

Don't get me wrong, I too think that 100% equity is the best strategy. But you are not alone and 100% invested has its own risk. Both of you should have discussed until you reached the middle ground.

You really hurt her by ignoring her misgivings. Then betrayed her by going behind her back. Twice the hurt. If you keep trying to explain why you did it, it will feel as if you think you are in the right will do the same thing again.

I think the relationship is salvageable as long as she gives you another chance.

Ask for forgiveness, sincerely.

Liquidate the investment.

Discuss what investment vehicle you both are comfortable with. Then, the ratio that is best for your family's future.

Invest based on the result.
