Hi, I'm new here but I've been through the same thing, many, MANY years ago.
I was very young, with one baby and another on the way when my then-husband dumped it all on me. I was shocked, hurt, angry. We had been planning on going to the temple and be sealed. He went one step farther and started bringing anti-Mormon literature to me to read. I was so desperate to save my marriage I read those books.
And my testimony GREW!!!
In my case (so this is what *I* know), his leaving the Church that first time had to do with him committing adultery and hiding behind the anti. Once he got caught and came clean, he came back to church. For a while. We ended up divorcing, in part because I wanted a priesthood holder and he didn't believe--AGAIN.
Long story short, he's out of the Church AGAIN after leaving his second wife (who he had been sealed to). He's on wife #4 and they're both involved in a church that is HEAVILY into anti stuff. My children and the children of his second wife suffer because he has no respect for their beliefs. One child of mine has followed in his footsteps and absolutely HATES anything to do with the Church. She parrots what he says and it breaks my heart because it's all lies--and there's nothing I can do about it.
For me? Honestly? I had a chance a very long time ago to walk away with my head held high and conscience clear. I didn't and paid (and continue to pay) the price.
I guess my advice, FWIW, would be along the lines of LM... What would you tell your child if THEY were in the position? I would also suggest making a list of pros and cons for BOTH options: staying in the marriage, or leaving. It's not dependent upon quantity of reasons, but the QUALITY. Ask Heavenly Father. He knows what's beyond the bend.
Good luck!
