Is this behaviour typical of a vanisher and what causes them to be this way? Also, does this behaviour reduce the chances of a reconciliation?
Somewhere in their minds they KNOW what they are doing is wrong; and some never intended to leave the marriage in the first place; but most KNOW that if they say anything; blowing the affair out into the open, they could find themselves divorced.
And some don't want that, as they know within their hearts they will return to the LBS..what they don't know is that it's possible the LBS might NOT want them back...they don't realize this until much later in the crisis; when
all of the damage is shown to them in living color.
This possibility should be a very scary thought; but if they do have that thought, it is "put aside" for what they think is "better things" for the moment...it's not something they want to dwell on, for they have convinced themselves the LBS will always be there for them...and the LBS in this instance is taken for granted.
Some of the secretiveness is selfishness on their part; some of it shame and guilt; but the excitement is to much of a "high" to give up, just yet.
For some, they wanted the friendship; but things went much farther than they intended them to go; and it's kept secret out of guilt and shame.
It's ALSO typical teenage behavior; and the LBS is viewed as someone who could really make trouble for them, if they knew what the MLC'er was doing.
You know, kinda like the girlfriend/boyfriend that mom/dad doesn't approve of...and they are intent on getting what they want, regardless of who it hurts.
Mine was NOT a vanisher; but his behavior in keeping the affair he had a secret was much the same; NO ONE had contact with his OW, but him...she was a dirty little secret that was being blown open by me; and the only thing he didn't realize was that HE was telling on himself the WHOLE time...I didn't know until nearly the end, that the emotional "signs" had there all that time...I just didn't see them until I started doing some research on the internet..and those signs jumped out at me; plus a whole lot more as he was trying to end it; and he, unknowingly, when the affair went physical, brought home evidence that he was and had been with another woman.
The above has nothing to do with anything; but secretiveness is a common MLC trait...they think they have it over on the LBS; not really knowing the LBS has ways of finding out what he/she wants to know, IF they really want to know.
