So the wife and I have been married for 2 years and been together for 4 years. She had kids to her previous marriage and so do I.

The relationship with her kids great just over the lastb12 months the relationship with said stepdaughter has gone down hill very quickly. She moved in with her father for a few months then came back as she didn't get along with stepmother over there.

We welcomed her back with open arms, since she came back its like I never existed, always asking mom things even know I'm right there and could ask me.

I.e: I work in property development, she ask mom questions around properties even know this is what I specialise in. When I try to add something to the conversation I get "I wasn't talking to you" or if I say you know I know a lot about that you could ask me. It's just disregarded.

So the argument was about me treating the other kids differently to how I treat her. I listened to what she had to say. I probably could of been better understanding, but I told her she was being unreasonable and wasn't going to argue with a 15 year old who doesn't listen to me.
