Good thing is you can have multiple wives in heaven if you become exalted. I love how this applies to ALL marriages.
LDS theology heavily promotes the idea that marriage and family are an important source of happiness in this life, not just the next. The doctrinal and afterlife san around a non-temple marriage are an entirely different topic, and one that I am personally much more at peace with than my questions about how one might make an interfaith marriage work in this life. And dating you are done with francisco, ask about best places and where she stands.
