OP it’s incredibly easy to make up bank statements.
Sorry but I am absolutely convinced that he is a scammer. And while on the whole I am in favour of just moving on in these circumstances, on the basis you’re pregnant I would hire a private investigator to look into all this properly for you.
If he has a high net worth then we’re talking millions, tens of millions, not a few hundred k, and you say that he’s too afraid of conflict to confront his ex/hire a lawyer? Come on, are you really that gullible?
Please tell me you don’t intend to give up work when this baby is born, because right now he has you exactly where he wants you. Pregnant, with the likelihood of him being able to walk out at any minute and leave you with nothing.
Tbh I wonder whether there even is an ex.
But trust me, nobody keeps millions of pounds in a revolut account. He is 100% lying to you about who he is, what he stands for, and what his motives are.
I suspect you were only meant to be a fling, but you getting pregnant scuppered that for him. I wouldn’t expect him to stick around though. And tbh I wouldn’t be waiting for him to stay or walk.
The ex is a red herring. Whether there is or isn’t an ex, I would get out now.
