I need help.. My mind randomly wanders remembering mistakes my husband has made.. I always wander whats stopping him from doing them again.. all I really have is his word.. I dont want to bring it up with him incase he isnt doing anything and then I just end up looking stupid but Im still scared of it now that we are having a family.. Would my husband ruin that?.. I dont know what to think :'(
