Questions: Girl's Behavior

Bear in mind she is 36 years old, so if she’s just way too old for you this post isn’t intended to capture the interest of 20 somethings , although it’s not an unpleasant thing on the occasion it happens haha

-I confessed to her 8 years ago, she was flattered but nothing came of it.
-We are now both 19, I moved on from liking her obviously.
-First time we hung out with all her friends (drunk), she told me "I love you" and added "but not romantically." She was very happy when I said it back.
-Afterwards she texted me something something 'babygirl' but said it was on accident, it was meant for her dog. (Im a girl too. we are both gay)
-She invited me to come over and drink 2 weeks ago.
-I watched her play Minecraft and she joked about us having a honeymoon and 'boning in the bonemeal bed'
-She made her friend move so she could sit by me.
-She insisted I wear her coat to keep warm and said "I would love nothing more than to care for you"
-She found out I'm younger than her and said "Oh, that's weird. But age doesn't really matter to me. Unless it's super young."
-When her friends left and we were alone, she said "I love you" again but didn't say 'not romantically' like last time. But after this she hasn't spoken to me in a long time. She's a terrible texter she says, but still, it's radio silence.

I don't know if I like her back or not, but I'm confused if she likes me, I feel like I'm getting mixed messages.
