I fucked up anons (Pic related)

I am 39 years old and last year lost my job. Now with a wife and three kids you would think that this was a big problem but luckily we have saved and saved and are very well off. So much so that I could potentially never work again but I thought I would not like to hang up my boots just yet, but I also did not want to go on doing the same thing again and again.

So here is this twist I decide to work at good old McDonald's because as a /b/tatrd I won't pretend I am better than that shit, why not hey? keeps me out of the house.

Now here is the problem, I have been there for almost a year and as you know (if you are from the UK) only teens to early 20's seem to work there. some of the lads (most likely as a joke) dragged me along for a night on the town, me and wife thought I should go just for fun. Anyway basically I fucked this girl who I work with, clearly a gold digging whore as I brought all her drinks but anons, this was the filthiest dirtiest sex of my life, makes my dick diamonds thinking about it.

So basically, what the fuck do i do? continue to cheat or throw away the best sex I ever had?
