Basically my partner claims he has never cheated. However there are a few moments where I feel I could dispute this but never had clear evidence. I went to the doctor's with a problem down below and turned out to have contracted an STI. My partner claims he has never cheated but I just can't see how I could have had or he could have had an STI for 5 years and two pregnancies and it never be detected?
What's your thoughts?
