So my sd 17 has been annoying me lately. She is immature and manipulates my husband into these stupid conversations and it annoys me!! My dh tells me to lighten up (which can be true) but he doesn't see what I see. Don't get me wrong, I love my sd but she is a typical teenager that will lie and manipulate to get what she wants. My dh believes everything she says and he's not able to look 5 steps ahead, the way you need to with these kids today. She can be disrespectful to me and it feels like my dh chooses her side. This fuels me and I made a comment to my dh that she will never move in here! My dh got very upset by this and proceeded to ask me why I said "yes" when he asked me to marry him. Trying to get my dh to act like an adult can be difficult! I'm not sure how to deal with this. Any advice???
