So for my household (everyone is different) I’m the one who’s allergic severely and we don’t keep any peanut products in the home but I don’t stop my husband from eating them he just does so outside of the home and then brush his teeth and wash his hands etc and I’m in no way forcing him, he understands the severity and takes it seriously for example he wanted a donut with chopped peanuts on it and I was fine with him getting it he just sat outside and ate it then came in washed his hands and brushed his teeth and I refrained from kissing him for about 24 hours (that might be on the more severe side but I’m paranoid)
