Not looking for judgement just advice/experiences from others in similar positions.

I found out 4 months ago my husband had a 1 night stand with 3 women (basically prostitutes/hore house as my councillor put it) while away with work. I was 8m pregnant when he told me but 6m at the time he did it. I have chosen to stay with him for many reasons. Obviously theres a lot more to it than this but I'm trying to keep it short. Looking to hear from other people who have stayed after there trust has been broken. I did a post before and got pure abuse and saying how I was dumb fir staying ect so not looking for that just ways to move for ward plus no one in our family or friends knows. X
