There are times where u rarely hear from him and then he contacts me. I'm pretty disturbed by the level of dismissiveness seen in many of the comments here. You are atheist and that's not changing. It'll reinforce the wisdom of running from this disaster in the making.
We all know that. This also means giving her something specific to do. I would never convert. Marriage to the right person is wonderful.
It sounds like you have found a good one. He says he hasn't loved me for the last 2 years and was only staying for the sake of the kids. She went ahead a married a non member. However, if you are a Catholic guy dating a Mormon girl, then remember that her parents may be averse to it. Find out what your partner thinks of as non-negotiable. I have been doubting if this relationship is going to work because I hardly ever talk to him so my first reaction is okay who else is he seeing??.
Don't do it girls, forget the "status" it doesn't mean jack. Lately we haven't been talking much as he doesn't want the "scrap time" that I have left over, but instead wants quality time. A lot of Mormons escape that pitfall and can put people first. And I don't have issues with her, hell, haven't even seen her in over 20 years, but the experience with the whole Mormon thing gave me better insight in to many things in life.
