L.S.
She's 18. I was there once. I HATED HATED HATED my stepmother. But after college and a few years after that I came to realize that my stepmother had her own issues and insecurities... we all did. And I see now that she really takes care of my dad and is there for him, etc. She has always sent us cards for birthdays, christmas, easter, etc. I now have a decent relationship with her. Don't push things. Just make sure your door is always open. You can't do anything. The more you push the more she will push away. Just be nice to her and if she is rude to you then it is your husband that needs to say something. Like ... Luka made this wonderful meal, the least you can say to her is thank you. I wouldn't make issue with your stepdaughter, but with your husband. You could tell her that you don't appreciate being treated badly and that the least she can do is pretend to be a nice person, especially in front of your little kids. 18 is still young. She needs to grow up and lose her resentment and anger. She is probably still taking out her parents divorce on you.
