First post in forever..and I don't even know the entire context of your thread SMW, so forgive me if this is repetitive.
I noted with interest the discussion about "guilting" your husband and the implication that you may somehow be rubbing church in his face. It is my very strong belief (and I can't speculate that it will help or hinder your chance at reconciliation) that you don't let what your spouse may potentially feel about something even enter into the equation. You be yourself. It's clear that you are a Christian woman and that your beliefs are a big part of who you are. You are also a very caring mother and it's tearing you apart what this is doing to the kids. It would be untrue to yourself to tone down your beliefs, or tiptoe around the children's issues, in order to potentially spare your husband's feelings.
Besides, there are tons of people on here who like to talk about what makes their spouse feel guilty, but does anyone really know? And are you responsible for your spouse's guilty feelings? You don't control his feelings of love, lust, unhappiness, or happiness, so what makes anyone think you can actually MAKE your spouse feel guilty? I do know that it's better for your spouse to want to come back because of who you are, and not who you pretend to be, or for things (such as your level of Christianity) that you are sparing him from.
