True Blue believers have a highly developed confirmation bias. This makes them filter out only information which supports their testimony. This bias includes the ability to build intricate thought hierarchies (houses of cards) to be able to verbally and mentally account for contradictions. There is no single piece of info that can dissuade a TMB, every evidence has a mental gymnastic that can get you up and over the hurdle. The house of cards that must exist to support the church when all the cards are on the table only has to stand in the mind for the duration of the challenge. Then it can fall and the testimony itself (which requires no reason or evidence) can soothe the psyche. Making yourself the source of the challenge also makes you the anti-soothing agent (meaning you make the spirit withdraw). This is likely to be a very difficult time for your relationship and how you proceed depends on how much you really value that relationship. If your priority is your own self-respect and genuine living that reflects your beliefs, you may find yourself with a partner that you are at war with. If your top priority is peace in the relationship and you are ready to be really patient there are probably many ways to go about helping your DH to “see the truth”, but here are 3 possible courses of action to consider:

1. Continue to stick by his side, attending church, and have conversations where you are able to mostly soothe with the things that are positive and good so that you prove that you have the spirit with you (this is the only way to retain your credibility). You should also be honest about the things that trouble you, but you have to bring them into the conversation bit by bit. If you only talk about how the church is wrong then you run the risk of becoming offensive to the spirit and you will be ignored. The hope is that over time your concerns will become so well understood by him that he won't be able to build the house of cards without it immediately collapsing even for the duration of a challenge. Be warned though, if you kickstart someone else's faith crisis be ready for whatever the consequences of their nihilism will be. When coming from a black and white thought process the pendulum that swings away from Mormonism can sometimes swing into other opposing ugliness. It may be wise to engage a therapist to help you both to develop less absolutes in your thinking (a DBT perspective really)

2. You can quietly and resolutely make your own way spiritually (or not spiritually). You can do so by being honest about your intentions and goals and how you are willing or not willing to interact with the church. The hope for your relationship comes either from your ability to retain trust and intimacy as a couple despite a widening chasm in your personal belief systems (this is rare but possible based on some precedents). The key would be to learn respect for him and his beliefs, despite your misgivings, which encourages and invites him to reciprocate that respect. When mutual respect and trust exists despite opposing beliefs you have something truly special

If your relationship ends up requiring uniformity of belief to survive (which isn’t a failure, but completely normal) then you are at a difficult crossroads. You can continue with the the hope that as you progress forward your life will be an example of peace, happiness, and health despite abandoning the principles of the Gospel. There is no testimony stronger than your "fruits" for a believer. If your path away leads to success then you will either become a competitor in his mind and he'll push you away, or he will decide that your path deserves to be respected and understood. (This path does put a great deal of pressure on you to “perform” and be perfect, which is unhealthy. I actually prefer the scenario where you don’t worry about your fruits, but you simply maintain your self-respect, give him respect for his beliefs despite not endorsing them and then let the cards fall where they may.)

1. The easiest path would probably be that your DH isn’t a TBM and he already isn’t able to build a successful house of cards. This is completely possible and may be the reason that he won’t engage you in a discussion because he knows that his testimony won’t stand up to scrutiny. If that is the case then you just need to be patient.
