If there is no OW or OM then they move from replay into depression proper and withdrawal proper. If there is no affair this part of withdrawal doesn't exist.
JA's right; the MLC affair actually LENGTHENS the journey; and the added stress of the affair and OW Withdrawal; not to mention the added GUILT the MLC'er feels as a result.
They do find it is NOT worth it as they work through the reasoning for the affair.
If a MLC'er has NOT had an affair; they will generally feel guilty for other things they THINK they have missed; but the movement is as JA describes.
I don't see many who hasn't had an affair of some sort; but the ones who don't have a strong, and deep core of belief, plus a healthy measure of SELF RESPECT...and though, they have the feelings they DON'T act on them.
I had that draw as I was going through my transition; but my moral code reminded me that it was NOT a good idea, as it was WRONG to do. It seemed, during that time the Lord had abandoned me; BUT it was one of the temptations for "something different" I had to face on my own; and overcome on my own.
So, I hid most of the time; as the feelings were that strong for a period of time.
It is part of the temptation the MLC'er/transition-er goes through and faces, when traveling through the tunnel.
Unfortunately; many take the "bait" the devil offers; and fall hard; sacrificing their self respect and destroying the trust and respect of the LBS in the process.
And the trust and respect takes TIME to rebuild; assuming it ever does...there are many who have problems getting past the act of adultery; only God can bring the LBS through to a position of regaining their trust and respect for their MLC spouse.
Anyhow; I didn't mean to hijack the thread.
