Define your relationships like this. What would that person do if they got a Billion Sats. How much do they value you? If the answer is 0. Then you probably are in the wrong relationship. Which is where I find myself.
Her money is hers, with access to my accounts my money is hers. She actually told me that if she got a billion Sats she would be out of here. When I would not have a problem sending her wallet 500 M sats. Till now. If you are with a woman think on these things.
