Christian men are technically only supposed to leave in certain circumstances regardless of what they married. I'm not sure if OP is Christian but I certainly wasn't advocating for cavalier divorces as much as I was echoing the Pauline refrain of it's good to not marry if at all possible. Given the current state of the dating market and society at large, it is reasonable to expect the Christian dating scene is filled with women pretending to be this, that, or the other thing because Christian men are "easy marks" who should be gamed, because they deserve it, because they're easy marks who should be gamed.

If you must, and especially if you have assets, the prenup is mandatory now. If she leaves you because she's mad she signed the prenup she's no longer you're problem.
