Welcome to mamapedia!!!
If you aren't married to your "partner"?? You can pick up and leave if you don't like what's happening.
Blood is thicker than water....he's putting his children first. If you don't like it? Leave.
If you want to make this relationship work?? FAMILY counseling. And that includes her...
have you tried walking in HER shoes? She's a teenager, so her hormones and emotions are all over the place, she's bouncing around between TWO homes and I'm sure that each house has different rules.
It's obvious you do NOT like her. I think it's because he puts HER ahead of you and you are jealous.
The dad needs to be a dad and not a friend. He needs to make rules and consequences for his children. If you are married, you have to be able to discipline her as well...within reason.
So the bottom line is this - if you are just living together? LEAVE. If you are married - ask yourself if you are better off with or without him...and if it's WITH? Then you need to pony up - get your family into counseling...set up rules and consequences....
if it's WITHOUT? Leave.
Good luck!
