Jealousy - Two Questions for Cucks and Couples

Was talking to a buddy today. We used to play with he and his wife a few years back but they were having problems and quit LS. He mentioned we are the only former LS couple he and his wife remain I connected to. He also mentioned feeling a bit jealous of his wife’s lovers.

in thinking about it, I’m more jealous of the lovers my wife took before we married and am not jealous of the ones she’s taken since (not being part of having pleasured her maybe?)

2 questions:

1. do you keep in touch with bulls or LS couples after you stop being lovers?
2. Any jealousy issues with past or current lovers?
 
We do stay in touch with one bull that has moved onto a vanilla relationship. I think he is more jealous of us than the other way around. He managed to fall for a woman that refuses to have an open relationship. He wants one but cannot find a woman that will accept this type of thing right out of the gate.
