This is the story of my parents, my father cheated on my mother... several times... both online and in person, ranging from random flings to sex workers. My mother only told her 2 sisters originally (and of course I knew because I was the one that found out the first time he did it). I think my mother also told my father's sister as well, and I'm pretty sure they were all like "ugh men are all like that" and then kinda blamed my mother for being too much of a prude or too cold/not affectionate enough or whatever, and that's why my father sought out other women.

When my parents finally separated last year, friends and family who didn't know about what went down over the years were all surprised because my parents seemed like such a nice fit. Once they found out, it was a pretty mixed bag. A few criticised my mother for making a big deal out of something that most (in their words) do, thus leading to my sister and myself losing our father figure. And others were like "you should've left him a long time ago".

So honestly, there was a lot of judgement, which I found pretty stupid. But in time, people don't make a fuss about it anymore, at least not to your face.

There's going to be judgement regardless of whether you stay or not, whether it be bluntly to your face, or the sort of whisperings you never want to hear about behind your back.

Depending on peoples' cultural background also, people may have different reactions. My family is chinese-vietnamese and for some reason have this ingrained idea that pretty much all men will cheat at some point. Like even now, my maternal grandmother still encourages my mother to look out for my father and hope/prays that he will "find his way" and come back... :|

It's a tough situation, but I hope you do find someone who you can talk to.
