Never been married so I have no idea what it is like to have one of my kids disrespecting me like that (well, I have a pretty good idea what I will do, anyways). Just reading off of your post, my first thought was maybe you are supporting her behavior unknowingly. It's your house so it is your duty to set the rule/tone, what needs to be followed. That kitchen incident, you should've just sat, have snack, let her know in action it's your kitchen. The whole resentment thing.. I would rather see the end of it, show my kids what's proper and if they have problem with it, then you go out and find your own place; but as long as you are living under my roof, follow the rule and show respect that is due. Again, I know nothing of how to raise kids/how to deal with adult children, etc, but hope that your daughter would come to her senses and start honoring/respecting her parents. God bless.
