Kind of Chick Lit

I always assumed 'Chick Lit' was a genre geared towards girls between 14-25. But some say, it's all about empowerment. I call my novel chick lit because it is for a young, female audience. It's about romance, but there's no sex, it's about high school cringe moments, falling in love at the wrong time, friendship blossoming and dying and about those who stick with you to the end. So, is my novel REALLY chick lit, or am I just kidding myself, and I am writing a romance?

It sounds like what you are writing is YA chick lit. It depends on how old your MCs are though. Are they adults looking back on these moments or are they teenagers?

in part 1 their 15-17 and in part 2 their adults with children of their own

Then it is still chick lit since it covers adulthood as well. Once you've finished your first draft, you may want to experiment with alternating chapters in the present and the past.
