Your AP is either getting ready to or is actively throwing you under the bus to save his marriage.
You need to decide if you also want to save your marriage. Because make no mistake, there is a 99% chance that the OBS will contact your husband. And they will piece together their own information via texts, emails, credit are/banking statements, and talking to others that might know. And if they do he will inevitably catch you in a lie. And when he does, you probably won't have a chance to save it.
seadoug105 nailed it. Take heed of the first sentence especially. If you read this with a clear head, here's the order of priorities for your boyfriend, his wife, family, job and then you, (maybe). He's looking out for himself. Your priorities seemingly, job, boyfriend, husband (maybe).
If your boyfriend's kids are aware and your husband works with both of you, there's literally no chance of him not finding out. It's best for you to inform him before Joe in accounting knows, as it will get around if it hasn't already. Six years, people talk.
The best case scenario is you're suspended without pay for a while or reprimanded and concerning your husband, I really don't know since you aren't too concerned with him aside from him getting hurt, which by the way is really not him getting hurt, but you preserving your image and reputation as an adulteress. You're in self-preservation in every sense of the word.
Your husband will be traumatized realizing his marriage was a sham and he actually shared you for 6 years. The responses can be varied. One very pitiful one is where he says, I want to reconcile. You have to remember when speaking with him after the news is broke, that he will be 100 times more confused than you are and will be devastated on top of it. But here's the thing. It's 100 times worse when he finds out more later, either from you, the job, boyfriend or boyfriend's wife.
Your future is helplessly out of your hands. The only thing you can control is your ability to release the outcome and come clean so that you have a clear conscience and allow the chips fall where they may. You may lose your husband and your job, but you knew this when this game started 6 years ago and never ended it. The results are where we are today.
Suggestions:
1) Tell every thing to your husband.
2) Draft out a timeline as to when and how it started and how you schemed to essentially fool him for six years.
3) Do not further antagonize and disrespect him by suggesting no sex happened. This is laughable and every adult hearing or reading this knows it. Secret adult lovers who work and travel together, don't skip sex for 6 years. Come on Lonelyl, think about this realistically. Would you believe if your husband said, I've had a inappropriate relationship with a co-worker for 6 years, but we never had sex. Believing you can convince him of this will further compound issues.
4) By going on the work trip with your boyfriend will reinforce to your husband who you have chosen. He will already have known though. You chose your AP quite some time ago and only him being married probably kept you married to your husband. Your husband knows he's plan b. Don't disrespect him by saying he wasn't. I'm not going on the fact that you had an affair, but that you never ended it and have yet to speak of love and affection for him, so he's a safety net for you.
5) Have mercy on your husband. He's innocent. Don't further humiliate and disrespect him by blaming it on him. You know this isn't the right thing to do. You're already in deep shit. At least try to keep him clean. His life has been destroyed. The least you can do is comfort him, not continue stabbing him in his back as you have done for 6 years.
