kml - Sorry to hear that you are reaching the end of your patience.
I think it's been discussed here and there in recent months but yeah - jealousy is very much a thing. I know that with B and I that she seems to have a fascinated interest in all my past history and I just feel rather uncomfortable with her own disclosures. She is also on good terms with pretty much all her former partners other than her first ex from more than 20 years ago. I find that that "green eyed monster" does lurk within me and need to swat him down reminding myself that that was the past and this is the now.
I'm not surprised at CMM's jealousy or paranoia. I expect that it is perfectly common albeit unreasonable. After all - he could hardly be expecting you to be virginal and waiting for only him. And as you said yourself and it had quite the impact on me, wouldn't I prefer someone who was caring vs someone who would just cast others aside.
Proof of fidelity is probably even harder than proof of infidelity. It comes down to trust and despite any amount of verification we all here know that it is possible to hide an indiscretion.
I know that you've examined your own situation and your own reasons for it continuing and you even posted a joking reference to being there because you can help him.
I know that any choice you make will be tough but I do hope you do it with your own best interests in mind.
