I am a first-time stepfather at age 45. I love my wife but I feel like her children (SD13 and SS10) are somewhat spolied. I say somewhat because I have seen REALLY spoiled children before, and ours aren't quite that bad. This does not, however, make it any easier when my SD13 decides to talk rudely or be patronizing to me. I feel like my wife doesn't support my role as an authority figure in the household, and only gets involved when her daughter complains about me. In fact, my wife tell me if I mention poor behavior on her daughter's part that "only children tattle" and that I should "act like an adult". Of course, when I say something her daughter doesn't like, she's instantly showing her disapproval. This sort of behavior from my SD is especially bad when the kids come back from a weekend with their BF, who is very wealthy and essentially gives her whatever she wants. My wife says that's just how it is and she has learned to just ignore it. Easy enough, but sometimes, I get so frustrated I have to fire back. Yesterday, on the way to dropping her off at her BD's house, SD was being (needlessly) critical of my driving, talking to me in an inappropriate tone of voice. I told her she should google "back seat driver" when she got in front of a computer. She complained to her mother, who gave me "the look" when she got back in the car. My wife and I have barely said two words to each other since yesterday, and I am absolutely seething with resentment at my stepdaughter, who in only a few short minutes in the car, managed to screw up the rest of the holiday weekend for my wife and I (we had to take her back to her BF's house after an activity that he refuses to take her to or pick her up from even when it is his weekend to have them. I feel like the only thing screwing up a perfectly good marriage is my spoiled bratty SD13. I think she might be happier if I would leave. I was so mad, I wanted to send her a nasty text (I refrained) telling her that her BM was mad at me now and ask if she was happy about it. I know ow I am supposed to be handling stuff, but sometimes it gets so frustrating because I feel like my wife doesn't support my role. It doesn't help that when we got married I moved away from my friends. It's her house, her church, her friends, her kids. I don't feel like I have any kind of support. I'm a good guy, and I have been working very hard to be a good husband and parent. I feel like I have given up everything, and now I find myself wondering after almost a year of marriage (1 year on March 12th) if I am not asking the impossible of myself (becoming a stepparent at my age after being a bachelor for so many years).
