Not sure how to handle this...

So I feel like my mommy protectiveness is already kicking in. My cousin is getting married in October and by then my baby girl will be about 6 months old. I can't stand my cousin's father (he divorced my aunt and did a lot of mean things to her) I really dont want to be around him but most importantly i dont want him near let alone trying to hold my daughter. I'm contemplating skipping the wedding all together but I'm not sure. What else can I do that keeps him without causing drama or should my we just stay home?
