To the OP: I've thought a lot about your post. Full disclosure here: I don't currently share your faith but have past experience from many years ago that helps me empathize with where you are.
I think that right now it would be best for to make your top concern your own mental health, instead of following the doctrines of a particular church or type of church.
IMO it would be best for you to seek counseling, both personal for you, and marriage, completely outside of and independent from your religious affiliation, with no involvement of anyone related to your church or religion. I realize that your church may discourage you from doing this and tell you it's somehow wrong...perhaps even kick you out for "disobeying" them. Please consider that this is because outside counseling that they have no involvement in would threaten their control over you.
It is possible that some in this church have woven you into a web of control, that you will never be able to untangle yourself from, by following their rules. They may continue to find ways to make you wrong and everything your fault no matter what you do. When this kind of thing goes on, it is NOT your fault. It is their own psychological need to control people this way that is the problem.
A community of faith should be helping you through tough times, as you ask for and consent to their help. Not making the tough times tougher, setting up mind games, causing you to doubt yourself, inserting itself into your private, personal life in a way that causes a rift in your marriage (ie your DH being more loyal to the pastor), and blackmailing you. This all sounds very, very destructive and unhealthy. I know you may be in a very self-doubting mindset right now, and thinking "but this church is more biblical". If it's "more biblical" than others, but less
loving, and it is hurting your, then I hope you can see your way to getting some outside help for yourself. You deserve to be treated with love.
