Step mother & 16 year old Step daughter

Made a great bond over the summer with my 16 year old step daughter she finally treated me like a mom and best friend in she 10 years of knowing her. I know she had the best summer and time of her life as I did with her. We spent a couple days of the week together through the summer. I put in the time and built our relationship up strong so I thought

Side note: I also realized being around her that i need a female around for me to feel my best and thrive.

Which makes sense growing up with a sister always around who is no longer in my life 99% my of my time is spent with my husband and 3yr son. We both work from home together and

My son is with us 24/7 too.

Anyway Now that she back in school she has distanced herself from Me we used to text every day now i am the only one to reach out and she wont even text me back or answer the phone when I call.I love her so much and i dont know what to do to get my daughter back! I NEED HER!

I need daughterly love.....where esle do i get it?

Can anyone relate? Step moms? Anyone? Help!
