In theory, this sounds like a fairytale, an ordinary guy turns out to be a multi-millionaire.
In practice, this means that he lied to my face the entire time, presumably got his family and friends to lie to me as well, because apparently the entire time we were dating he thought that I might be a gold digger?
Creating an entire separate identity because of your gold digger paranoia doesn't seem like a healthy behavior.
1. Use a fake name.
2. Create a fake story as to what he's been up to for the last five years professionally.
3. Get an ordinary apartment, car, clothes, etc. all for the purpose of appearing to have regular income.
4. Get his friends to support his fake name, fake life, fake career story, etc.
5. Get his family to support his fake name, fake life, fake career story, etc.
You don't think all that counts as lying?
2. I don't talk about work, it's rarely a deal breaker.
3. It's a normal thing to have a pied-a-terre.
4-5 Don't mix your friends-family and your date until you are sure in them. Actually, get an apartment on a different coast.
No, I don't think it's lying. And it's easy to do for someone with 8-9 figures in a bank.
