Im mormon he is sikh?

Respectfully have you taken this issue to the Lord? Do you wish to be married in the Temple? And having your children raised as members of the church as well? It isn't likely if you end up marrying a Sikh. You should also talk to your Boyfriend and tell him of your religious commitments. Reading up on the Sikh faith some, via Wikipedia, it is hopeful that he might understand. Religion can cause a lot of problems in any relationship, let alone being Mormon makes it a lot more difficult in regards to religious obligations. Remember it is mentioned in the scriptures that you should not be unequally yoked with someone who isn't a believer. With that warning in hand, you have a choice to accept it or ignore it.
