It depends on if you plan on having children. I am Jewish and my husband is Christian. We are happily married so it’s clearly not an issue. But we are not having kids together. (We do have kids from first marriages).

Prior marrying my husband I had a long term significant other we lived together with and he is Muslim. Again no faith issues but again we had no kids together.

I’d not be in inter faith relationship if I planned having kids with the person unless they’d be ok with me raising kids Jewish as it’s important for me. So for me it boils down to raising children.

If you potentially thinking of raising children with this person then I think it might be an issue. If not, I personaly am ok with being in inter faith marriage. We try to incorporate both our traditions into our lives
