Step Mama Blues😢😢

I feel like i’m nobody .... im super nice to my stepdaughter and listen to her and try to involve her in our everyday lives. She’s 2 currently. I know she’s a little kid but she acts like she hates me and my husband makes her say I love you to me and I don’t want to force her to love me or force her to be around me. Her mom hates me and that’s totally fine I could care less. But I do want her to like me... she means so much to me and I really do love her. It just sucks feeling like your nothing and nobody ... I don’t discipline her or anything like that.... if there’s a problem I tell my husband. Is anybody else a stepparent?? How do you handle it? I feel like no one understands me😭😭😭😭
