My husband and I got married about 3 months ago after being together for 6 years. He has a daughter from a previous relationship, she is 8 going on 9 very soon. We've had some great times together over the years but there are so many days when things are very challenging with her. For example she takes every opportunity to test me when her father is around like making up stories about me yelling at her or name calling, when I don't. I feel she's too young to understand how to manipulate people and situations but I'm not so sure that she is. She even acts like I'm not around, she becomes very non responsive when I try to have a conversation with her, she just doesn't reply and doesn't take much interest in me unless I have something material to offer her like a toy etc. she shuts me out and it's really hurtful. I try my hardest to make sure we both get along but it's become so hard in recent years. My husband and I have had many fights over her. I really try my best to be a good stepmum. I really feel she has a wall up and just doesn't let me in. We've even decided to tone down any affectionate acts like holding hands and kissing around her as she becomes very jealous and seeks attention from him when he very briefly turns his attention to me. My husband accuses me of not trying hard enough with her but I feel I've tried my hardest with her for a long time now. I want us to get along, I'm married to her dad and really don't want the animosity between us anymore. I've even discussed with her dad and I want to have a baby and asked if she would be excited to have a brother or sister, she replied 'No, I want to be the only one'. Can anyone give me some advice on what to do.
