If your husband lied about having a facebook

What would you think , and everyone knew but you ? Found out on my own and I don't even have a facebook and this girl that said she wanted to kill me and my son six years ago liking his photos , claiming he hasn't talked to her since ?

Because I was pregnant with his kid which we have a 6 yr old together . She didn't like me for whatever reason and I never met her oh and to top it off he had the nerve to invite her to our wedding , she never came thank god . I found out he was bringing my son around her for a whole year behind my back and foind out her invited her to our wedding a year after marriage.... I neber snooped
