I completely agree with this. Since Feb. of this year, there have been 4 marriage breakups at the club that David and I go to. 3 of them were long term (25, 21, and 15 years) and the other was still relatively new (2 years). All of them were affected by what VegasLee has stated here. I'm sure that this isn't the only thing that destroyed these marriages, but it caused the cracks that were already in the relationship to become doors that others were easily able to walk through. Instead of stepping away from the LS to work on their marriages and reconnect with each other, they found it easier to find comfort and affection with someone else. Their communication with each other broke down which caused a breakdown of their marriages. Being someone who doesn't participate, I'm able to observe people and I can say from an outsiders point of view that yes, if you have a solid marriage, swinging will do nothing but bring added pleasure to it, but if you have the smallest problem, it can blow up in your face. I'm just sad that in all but one case, there are children involved, not to mention threats by one of the couples to "out" each other in court and name names in the process.
