From a Jain point of view, marriage is a personal and family matter, but the main concern is whether the relationship helps or harms the practice of Ahimsa, self-discipline, and right conduct.

A Jain who is vegan marrying a non-Jain who eats meat is not automatically forbidden in Jainism. However, it can create practical and ethical difficulties, especially if:

• meat is cooked in the home,
• there is contamination of Jain food,
• household habits become a source of conflict,
• one partner’s lifestyle weakens the other’s vows or discipline.

If the couple can live with mutual respect, and the Jain partner is able to maintain their principles without compromise, it is generally seen as more manageable. But from a Jain spiritual view, it is always better to choose a spouse whose conduct supports ahimsa, restraint, and purity of life.

So the answer is: yes, it can happen, but it is spiritually less ideal unless the Jain vows and values can be fully protected.
