Hi,
Try this.
①Here is a photo of me and Autumn! I was happy to get the chance to hang out with her while I was in LA. I missed seeing her when I was in LA. But I am planning another trip to LA later this year. I would love to chat with her over a cup of coffee then if she is available!
At the end of line one, you wrote her. So, I changed all of the "you" to her.
Cheers
