It is absolutely true that standing may be the wrong option for some people. Nonetheless, with MLC I would never suggest to someone that they should "stand" or that they should "divorce". The decision on how to deal with the complexities of MLC lies with the LBS.
I guess that what is at debate here is more a question (which different people answer differently and this site, to some degree, allows for that) about what "standing" is.
For some, it is taking a moral stand to maintain an existing marriage and uphold existing marriage vows despite the fact that the MLCer is not doing so and has left the marriage. The more you adhere to Christian doctrines about marriage, the more likely you are to be in this first group, I am thinking.
For others, it is simply a decision not completely slam the door shut on the possibility of reconciliation one day by maintaining a civil and compassionate attitude to the MLCer, but seeing the marriage as completely finished from the moment the spouse walked away from it. For those who are spiritual, but not really religious (or even agnostic and atheist) it may be more likely that we see things in these terms, although I am not making a blanket rule!
RCR does state that this site is based on Christian principles, and I accept and respect that, but she also states that people dealing with MLC who are not strict Christians are welcome to join and I think that this is great because what we share in common as people is greater than the things that separate us. We all loved our spouses, we all desired monogamous marriages based on trust, respect and love, and we were all surprised and shocked by MLC and its repurcussions on our familes and each other. We all need support and direction and 2x4's - but those things can be given with compassion and consideration, rather than judgement and condemnation.
I think that it is fair to debate these points, and of course we can not ever get far from the issue of divorce as for many of us it is a reality that we face everyday. However, I think that we can become so focused on our own point of view about who constitutes a valid or worthy stander that we narrow ourselves of to the great wealth of insight into human nature that a broader set of ideas exposes us to. We do not have to agree with each other, but I think that it is important that we try not judge each other too harshly. We are all dealing with the same thing, but we are also all living very different realities from each other and it can sometimes be easier to judge and condemn than it is to show understanding and compassion. I realise a fault that I often had within my marriage was a rigidity of thought that sometimes blinded me to another person's pain. I thought I knew all the right decisions and all the wrong decisions and that I would always make the right choice. I was arrogant, and I was wrong. None of us really know how we would react if forced to live out someone elses day to day reality. We think we do, but we dont. Honestly, I thought if H ever cheated I would slam a door in his face and never let him back. But at BD I asked him to stay and try to work things out...
