Asking for a friend:: my friend's wedding is upcoming in September and she invited a friend and gave her a guest thinking she would bring her boyfriend. However, in a twist of events, this girl broke up with him and is now dating her previous ex/ baby's daddy who is not a good guy (previously emotionally abusive to her , at one point broke into her house and cut up all of her bras and underwear, overdosed on heroin 3 times in a matter of months (2 times in the presence of their 3 year old daughter), type of not good guy, also years ago he was smoking pot at another friends wedding and stunk up the whole venue). The girl insists her guy has changed (he has been on court ordered probation for 2 months now due to child endangering) but for obvious reasons the bride cannot stand this guy. Should she just let it go and let him come or tell her that she can't bring him and how would she say that?
