I say that either she lies or not, the most important thing for you is not uncover the truth, but to realize which will be the decision that will not give you regrets. Even if she is playing you and the marriage ends up as a disaster, you will still end up wiser and stronger through your experience. If you choose not to trust her, lose contact and beat yourself up for the next years to come, I don't see that as a win.

The real question is: do you really love her? Are you ready to put your money on the table? A life worth living is not a riskless life, but risks taken for the sake of it are not how a life should be lived.

No regrets, that will be what decides the good answer. Not the safety of your bank account. Think deeply and good luck.
