I dated a non member for several months, during the time of my meeting with missionaries, baptism, etc. At first it was very easy because we were just classmates. Then it was becoming harder because of conflicting beliefs. He wants to do this, but I cannot do that because of my own beliefs, and because of the Church.
When we were getting a little more serious, it became terribly hard to study my scriptures, go to church on time, etc. I ended up praying, and praying about what to do, and I ended up having to leave him.
The thing is, I was able to make him understand more about the LDS church and often times I felt that I may have "changed him" but he will never be interested in joining the church. I decided that the next boy I date will be an active member. Comments I received from him like, "Damn, why the hell are you going to church again? You went last week!" Was getting very tiring and old....and it needed to stop.
What helped me I made a list of what he did I liked and what he did that I didn't like. He lost terribly with a score of 7-39....
