Sorry about jumping in here but here's what I think.
First, this is not about you or your marriage. It's about your husband, his crisis, and what he thinks he needs to do. Anything you do that seems to get in the way of what he thinks he needs to do will be met with monster and/or will be used by him to justify what he's doing. Anything else that you do simply won't register with him because at this time you are not a part of what your husband thinks he needs in order to feel better. It's like he's indifferent about eating broccoli and you threaten to take his broccoli away. So what?
Second, boundaries are to protect you, not to influence the MLCer. It's more likely that the boundary will have a negative impact on your husband than a positive impact, especially early in the MLC. You put boundaries into place to stop the negative impact your husband's actions are having on you and your family. The only time a boundary may have a positive impact is when your husband is well into the crisis and is beginning to consider the possibility of returning. Then it might influence him by scaring him into believing that if he doesn't do something soon he could lose you. Even then, I would consider it to be a negative impact because it may cause him to return before he's ready, potentially leading to a failed return.
I totally agree with Brain and want to say, and I hope any newbies reading the boundaries and NC comments do it, whilst bearing in mind that everyone's stories are different, their marriage, their personalities and their MLC experience.......
So when you read this stuff please remember that and do what your instincts tell you is the right thing to do for your MLC'er and your situation.
As I have said a number of times, it is my opinion that there are distinct personality types and if your MLC'er is someone who has low self esteem, hates confrontation and is very insecure, all NC does is breaks any chance of communication in the future.
Now if your MLC'er is a bit a a narcissist or very sure of themselves, then NC can work because nothing will make them stop contacting because they have a believe they are more important than anything.....
NC is fine if you need a break from this, if they are monstering, if you feel you cant cope BUT if you keep it up and your MLC'er is a low confidence type before MLC you may also find, they then think you have given up on them, that maybe they don't deserve you anymore, or they should just leave you to find someone else....
So whereas I think you should leave them alone as much as possible, I also feel you shouldn't let the contact drop completely.......
In my sitch my H started out as clinging boomerang but 7 months in, due to OW pressure he dropped contact and ever since we have gone as much as 3 months without talking (we don't have kids so there is very little reason to talk about day to day things) BUT on my therapists advice I have occasionally contacted him (when there has been something relevant) and it has lead to some very good touch and goes with very revealing information which I have documented....but in the main I think its good to let them get on with it, but not to the point you move in complete opposite directions...........
just my opinion
BTW Def thank you so much for your insights there were bits that particularly hit home for me in my situation currently. I have done a huge amount of research on this and collated a big post on what previous MLC'ers have said about the fog, tunnel and their journey but new insights and experiences are always so good to read.....
And I totally agree with what you said about Lettinggo's posts, I found them last year and I totally agree with you on how amazing they are.
She was a really gutsy woman with some great observations and I have mentioned her several times in my posts.....I don't know how her story ended but If anyone deserved a happy ending she did.
