How is this any less of a real reason? If she believes in God and he doesn't, then Bible is pretty clear that they shouldn't be together.

@53, there is some dispute on that regarding the content of the Pauline Epistles, both encouraging the faithful to seek marriage within their community (partners should be equally yoked) but also upholding the sanctity of marriages between believers and nonbelievers and specifically telling NOT to dissolve those marriages. Whether you put the emphasis on the encouragement within or the upholding without varies. This is assuming she IS Christian, which really wasn't established here, and that he isn't, which ALSO isn't established here. Moreover, she didn't actually say "my religion doesn't allow romantic relationships with nonbelievers" or "I want to date inside my faith." She said "We can't date: God said so." The first two are things would not be unusual on a personals ad, the last makes it sound like God looked down at OP and said "nope, try again." Sorry OP, FYL

No they wouldn't, the reactions are clearly blaming her, and they would do the same if the guy broke up with the girl, claiming that God told him to.

Why can't people leave gender out of anything ffs, 'but if it was the other way around..' Well it's not the other way round, offer something insightful to an actual problem instead of making pointless assumptions
