Instead of planning to meet up with Mike you should admit what you did to your husband and try and work through this to save your marriage.

You won’t, but that is what you should do.

People in happy marriages don’t kiss other people. That kiss wasn’t “out of the blue”, it never is. And wanting to meet up with him is just going to end up in sex or crossing another line that you shouldn’t. You’re not clueless, you absolutely know how this is going to go and you are setting yourself up to progress the affair while telling yourself you won’t. Get yourself into therapy at the very least. Hopefully your therapist can figure out what is wrong with you and get you started down the path of fixing yourself. The only way out of this without destroying two families and many more other people is to admit to your husband what you did and get into therapy. It’s highly likely you will need to quit that job as well. And because all of that is SO much harder than just carrying on and falling into the affair that is what you will choose. Your poor husband and kids are going to be blindsided. I hope you make the right choice.
