So we been together 3.5 years and just found out he cheated with a co worker when we had been together less than a year

He thought I was planning to get back with my ex which I wasn’t but also I was pregnant

Now it’s bad very bad and don’t agree with cheating no matter what. We have since had another child and he is a lot different since had the boys

Would you risk giving it another try or not? He is very remorseful and changing jobs everything and saying he will ring me all time if not with me but also will do anything to prove he’s changed
