Gaisha house

What would you do if you where up pumping for your 7m old; your two older kids are getting ready for school while your husband slept in and you found him looking up reviews on Google about a gaisha house.

Back story. We all have a past he was a single father for years before I came around. He admitted to paying for sex. It has never bothered me and I told him that we all do what we need to do.

He knows I don't remotely play with any for of cheating which he is aware of. This isnt the first time he has done similar "stupid stuff".

The only reason I am sitting here questioning what to do is my children. If we had no kids I would have gotten up and left. Right then and there.

I've spent my life watching my mother get cheated on. I will not spend. My life being cheated on.

Please an insight on other women's opinion

UPDATE: it is a whore house I know this because this is where he went. I'm not assuming I know what it is by his mouth.
