I'll tell you something interesting; reading this thread brought a memory or two back for me.
I'm 4 years and 2 months younger than my husband...he was 37 when he started through the tunnel.
When I was on the other board so many years ago; I was one of the youngest people there at that time...this was back in 2002; the people I was counseling were in their late 40's, early to mid 50's and there were a few that were actually in their 60's.
At first some of the people were mad at me because here was a young whippersnapper advising the elders; and wisdom is supposed to belong to the elders.
In time, when the advice I was giving was actually WORKING for each individual situation; they were more apt to listen to what I was advising...I was 35 at that time...having been 33 when his crisis started.
Here, in the present time; I'm advising people again; only this time, some are older than me, some are actually younger than me.
That's quite a difference from years ago.
On the other hand, OP is right; this is a coincidence that some of the women are older than their husbands...in fact; I did remember reading somewhere years ago, that it's actually good for women to be up to 7 years older than their husbands; as women tend to live longer than men.
Just sayin'
Oh, and while I'm thinking about it; in regards to OW/OM;
it doesn't matter what they look like; it only matters what NEED they are meeting within the MLC'er...the affair is all about NEED within the MLC'er. The NEED to be accepted, the NEED to feel special with someone, an emotional NEED to be loved; even if it is not the right kind of love; even the NEED to be accepted for who they are.
As they are different their needs are different; and they choose someone who meets those changing needs. They will NOT allow the LBS to meet these needs, preferring instead to get involved with someone who is as neurotic as they are.
That's not to say they won't change back or turn back toward the LBS; but that is how they are and feel for that time in their lives.
Remember they are selfish, thinking only of themselves and their own needs, not caring who they hurt to get them met, even to hurting the OW/OM; just as long as THEY are satisfied, and "happy"..but this doesn't last.
There should come a time when the affair no longer meets their NEEDS; and it becomes unsatisfying to them...and that sets them up for breaking it all down.
Have a good one.
