That's a very good point to emphasize Delta and I don't think it's this thread that I said it on but it's why "no contact" can't just be considered an "event"...instead it's a lifelong commitment that must also entail a PLAN to be effective in order to minimize...
Contact of any kind will cause suffering. It is a fact.
For example...even though it's been 9 years and for all practical purposes you KNOW it's not going to rekindle...do you have a plan in place for the unlikely event that your husband runs into her at say, the grocery store or airport?
What's he supposed to do?
The ANSWER - DO NOT SPEAK TO HER. Literally get away from her proximity as fast as reasonably possible and call your BS immediately. Hiding the contact to protect your spouse would be a HUGE mistake....just call and share it and together we'll get through it. ****
You see ANY COMMUNICATION even just a polite "hello...how are you, good to see you, gotta run" carries with it a distrustful glow. The BS wasn't there. They will trigger and regress back to the DDAY and their imaginations will fill in the gaps. The will wonder things like:
1. Did (fww/fwh) say more and they aren't telling me?
2. Did they exchange business cards, emails or new telephone numbers?
3. Was the "contact" arranged?
4. Did they tell me EVERY SINGLE WORD exactly as spoken and in the order spoken (this alone is reason to run away without saying anything because rarely are conversations remembered PRECISELY and any change WILL be noticed by a NOW hyper-focused and aware former Betrayed Spouse)?
5. What non-verbal communication went on (what were they doing with their eyes, did she/her smile, wink or anything, did you check her out, what was she wearing, what were you wearing, did you touch her, did she touch you?
The speculation becomes endless and the "SUFFERING" will be evident.
MOST recovering couples aren't aware of this. Only being here on MB would really make any one aware that "no contact" really goes beyond just ending it and requires a plan. Without a "no contact plan" the tendency of most persons is to be polite. If they don't have a clue they are SUPPOSED to run away...they'll freeze while they consider what their options are and process WHAT TO DO.
If you have a plan in place...processing isn't an option.
RUN AWAY and DON'T SAY ANYTHING. Being rude to the OP is FAR FAR FAR FAR FAR FAR better than causing your spouse to suffer.
Mr. Wondering
***Any any Former Betrayed Spouse whose Former Wayward Spouse calls them immediately to report contact but that they responded according to the plan should be commended and NOT punished. This is practicing extra-ordinary precautions at it's utmost limit. How you respond to your FWS at this moment is CRITICAL to recovery. If the contact was truly accidental and such spouse responded according to your plan then you have absolutely nothing to be upset with him/her about. You MAY trigger a bit having the OP in your proximity and "suffer" a bit with flashbacks of dday but TRY not to take it out on your marital team member that stuck to your marriage's playbook. He/she is the good guy now.
