I am dismayed by so much advice given that the only way for healing to occur is to stop any contact with them, to look at everything they do as being "monster" towards us and the lack of empathy and understanding for what they are going through.
I think saying "the only way" is an overstatement and one I have seen before and one that I object to. In my own journey, a person of one, a period of limited and then no contact literally saved my life and sanity. I respect myself for navigating what I needed at that period of time so that I could survive. There were many other things I did to survive that I don't need to do now, thankfully.
For me, a person of one, it helped me detach from his instability, high narcissism, and his deliberate attempts to elicit a reaction from me when I was barely living from moment to moment, barely living from hour to hour, barely living from day to day. To underscore this, I lost about a quarter of my hair during that time.
For my own healing, I needed to separate from the chaos, instability, and selfishness to save my sanity and heal. I, an example of one, needed room to think and understand the tsunami that just hit. I needed time to look back at the actions that I couldn't understand before, but were troubling, leading up to BD. I needed to protect myself financially, even if I understood he was going through a crisis and needed as much money as possible to build his new life. I didn't sacrifice my financial future because of what he was going through and most LBS advise the same.
I also didn't sacrifice myself emotionally and mentally. For that period of time I needed to focus on my healing. I respect myself for recognizing and implementing that. Do not be "dismayed" for me and what I needed to stay alive and become a whole person again. Do not be "dismayed" that I think others may (the operative word there is may) need that space to heal. I don't view myself as some particularly weak, bad, or insensitive person.
What the LBS needs and their healing is most important. We didn't cause the MLC, our marriages didn't cause the MLC, we can't fix the MLC. But we can control ourselves, get our feet under ourselves and build a life, with or without the MLCer. For me, a person of one, I needed limited contact for business purposes only for a period of time. I needed to focus on my physiological response of high anxiety and learn how to reduce that (for me, exercise and limited contact). I respect that taking actions that help us heal can, for some (the operative word is some), include reducing or stopping contact for a period of time. That was definitely the case with me and I stand by that and look back at myself with pride on how I chose to heal.
None of what I said above means that I was vindictive or mean to the MLCer, and I don't advocate for that. I did need to be clear eyed that the MLCer was no longer playing in the same sandbox as me. I did need to be clear eyed that the MLCer was not treating me with respect. I did need to be clear eyed that the MLCer would have been happy for me to hand over all the financials to them for them to spend. I did need to be clear eyed that another person was part of my marriage and he was now in the sandbox with that person. I made the decision early on that for me, I was not going to be an OW to the OW.
I think that there are stages the LBS goes through in their own healing. The LBS is not a martyr. The LBS is not able to fix the MLCer. The LBS does need to respect that the MLCer is an autonomous adult who may be making poor choices in the eyes of the LBS and even others, but is allowed to do that. As much as it hurt me to realize this, the MLCer is allowed to love someone else and build a life with them.
