Living... I actually don't think that reading other stories here about affairs will stop you in your tracks. I really don't think it's going to make a difference to you.
I'm not going to flame you. My best friend was where you are and is living a sort of 'half-life' now. She was like a toddler-pulling-a-plate-loaded-tablecloth-off-a-table. All the warnings didn't stop her and it won't stop you.
I know what you want. You want to know how to manage yourself to keep it so you are in control. You also, I think, want a little 'camaraderie' from other women in the same position. You won't find that on this board because OW/OM (as they are so delightfully monikered), are generally - and often gleefully - flamed resulting in lots of deleted posts. This is because there are people here who are hurting, having lost the lives they expected. I can fully understand that and you should acknowledge that by tempering any responses you make to an obviously hurting poster.
At the moment, you still have control but I think you're kidding yourself. You say that you've told your married man that you wouldn't leave your partner for him. That is incongruous with your statement that you 'would happily clean the toilet' forever. I can see that what you feel is complete intoxication, I think affairs do that, they fill whatever that need is inside yourself.
If you PM me, I'll send you 'The Anatomy of an Affair', it's interesting reading.
In a nutshell though, you're not going to take advice about no contact, deleting his details, distancing yourself, etc. because it feels too good to stop it and you figure that if you don't get found out that nobody will get hurt. I'm on the fence with that one, it depends how deceitful and skilful at it you are - and ditto for your married man. You have to be very, very sure that you can count on each other to maintain complete secrecy if you're going to go down this route. Make no mistake though, Living, there is no turning back and you may well rue your decision to embark on it.
