I’m a horrible stepmother.

I feel horrible just typing this out but I need advice. I married my husband knowing he had a daughter and was ready to accept everything that came with it. I was ready to accept the “step mother” role or so I thought. His daughter is 4 almost 5 and she’s the cutest. She’s a hardcore daddy’s girl and everything she does, she has to do with her dad. She is connected to his hip. Sometimes she makes me feel left out 😭😂 Lol but She also loves playing with me. She loves communicating with me about the weirdest things. She even called me her best friend this weekend 😭❤️ she gets so excited to see me, but is it normal for me to not feel a “motherly love” towards her?? It’s not that I don’t want to or that I don’t like her or none of other crazy sh*t, but I see her more as my little friend. Don’t get me wrong I want to feel this motherly love towards her and accept her as if she was one of my own, but I can’t at the moment and it makes me a bit sad. It’s not more so that i can’t; I just don’t know how to. Like my husband will say “your daughter is calling you” and it throws me off sometimes. I just feel like it is sort of a disrespect to her mother saying stuff like that. I don’t have kids of my own which is why I think this is harder for me in a way, but I still feel guilty. I guess I’m just wondering if this has happened to any other stepmothers? Will I eventually get the motherly feeling? I must add that we only see her on the weekends because that’s the schedule her mother has with my husband. Which is another reason why I feel like I can’t make this bond with her because I don’t have enough time maybe? Any advice please!!

Also, sorry if this isn’t the right group to post this in!! Don’t know which other group to post it in
