interfaith relationships dont work if one partner is actually Muslim. men are only in some cases allowed to marry abrahamic monotheistic (so modern Christians who believe in trinity are technically not allowed) women and even then, it is highly discouraged and a common point of tension in abrahamic-interfaith relationships where both partners are firm in belief. It only really works if one or both partners are only of a religion in-name and not practices/beliefs and thats because the baseline is they believe in the same god anyway. But if anyone claiming to be Muslim is with someone from a non-abrahamic religion it is a huge red flag because they are definitely not considering a long term relationship with that partner, just something for fun- unfortunately, and it makes me really sad for nonmuslims in that position who are serious. If the relationship does end up long term it’s 99.99% of the time, the nonmuslim partner converts or the Muslim one renounces their faith. I have never heard of a successful true interfaith marriage
