For myself, I have had the hardest time with this one; because I just don't understand how someone can do this to their spouse, and just shut us out of their lives.
While within a fog that is so deep they have no compass to guide them; all things are shut out of their lives; and feelings that were once so strong, are buried deep within them.
This is an aspect; I have never really understood, although I experienced this, too, when I was in transition...it was like the feelings I had were "getting in the way" of my growth while in transition; and this is probably the most understanding I will ever be able to give; this is one of the unanswered questions that I had to let go of; because it was beyond my own understanding.
This is all I know; it is one of the aspects of the crisis/transition that must be outlasted and overcome by both the MLC'er and the LBS; if the marriage is meant to rebuild into a new one.
The "old" feelings don't contain the knowledge of what love really entails; this is another thing I know; as the resolving of the crisis means they learn to love in a way that was unknown to them, before; but they learn of sacrificial love; and aspects that are new to them; and they gain a better understanding of what love actually means; so, it would seem the "old" feelings would be overhauled to become "new" feelings.
This is but part of the emotional "overhaul" they go through to become a new person, IF they allow the crisis work within them; and go through the process to the end.
The "old" feelings, right along with the "old" person must go; everything changes within; and becomes new; again, IF they allow the crisis to work on them, and go through the process to the end.
But until that emotional overhaul begins to happen; their feelings are buried deep within; and they shut out, their spouse, their children, and their extended family; PLUS, any friends they had before the crisis...these are all part of the "old" life..but the reconnection, when/if it happens; begins with the friends, the extended family and the children FIRST(not necessarily in that order)...the LBS is always last in line; although having been first in being disconnected from.
I saw so many positive changes in my husband's feelings; and in his love for me; it is NOT simply words, now; it is balanced within his actions designed to make me FEEL loved by him; and he knows what love is all about, now, whereas he did not beforehand.
I hope this helps; the crisis is an emotional one, a hard battle that involves the light and dark sides of the person going through; and it will mostly be the NEGATIVE side of them that's seen during the deepest times in the tunnel.
It is HARDER to be positive, than it is to be negative; but the negative must be balanced with the positive, as the process of the crisis brings their emotions into a true balance; something they hadn't been able to accomplish beforehand.
They were either hot or cold; and had never been shaken or mixed together for lack of a better word.
It is similar to emptying a bottle of one chemical; and refilling it with a mix of two or more chemicals; plus a measure of the original chemical, that creates a better balance within. It involves complete change; although some of the "old" may stay; but not much of it.
Dang, after all that; I'm starting to understand this more.
Hindsight is still working its "magic" on me. LOL!!
But, even IF you can get your head completely around this concept; what can you DO about it? That's right, NOTHING; so you get to work on yourself; and leave them to twist, right along with their shut down emotional health, way out in the wind.
That's what I had to do; let him go, and let God work on him; while I worked on ME; and trusted Him for the outcome; however, it would go.
I hope this helps.
