these things happen and i know what it feels like but love is not some thing one can buy its a living thing,i might be passing trough the same thing but if she "LOVED" him at least or she still have feelings for him she must tell him rite away cause silence kills and if there is no spark there is nothing to do,but from the other side if she really love him and can accept his kids she must follow her hearth and not being afraid from a nagging woman ,just face things and live your life but the choice is yours
