AIO? I 21M have a confusing dynamic with my friend 32F. I feel like she keeps sending me mixed signals.

I’m 21M, and I have this 32F friend I met online 4+ years ago. We only met IRL once (5 months ago), but we talk and game (Dota 2) nearly every day. Over time, she became my closest confidant. She noticed when I was depressed and supported me through it. She has also opened up to me about her own mental health struggles, including suicidal thoughts.

She has a kinda extreme sense of humor that I usually join in on. When we traveled to an event together, she and a friend joked about “Cosby-ing” me, then later she “joked” that she peeked at my junk while I slept. She also tucked me in, read me a Dota 2 hero description as a bedtime story, and made jokes about “drugging me so I wouldn’t remember her sucking me off.” I play along with these jokes (e.g., when she said she peeked, I responded, “Couldn’t resist, huh?”). Sometimes she also jokes about me jerking off to her pics or makes jokes about wanting to become my step mom or fuck my brother.

At the same time, she randomly throws insults at me, like calling me cringy or embarrassing in front of our friends, but refuses to explain why. If I push back, she dismisses it with “That’s just my opinion.” 

She makes a big deal about my age, saying things like, “You’re a kid until 26.” And that she doesn’t want to talk about dark shit with me because she says it's bad to “spoil the world for the young lad” but she still does open up about things like fear of sexual assault and suicidal thoughts like i mentioned before. She also complains when I match with early 30s women on Tinder, saying “that’s too big of an age gap.” And says that she would feel guilty dating someone younger than 26.

When we met in person, she kept touching my hair, saying she was jealous of it and that I looked better IRL, specifically saying I “looked 26.” She asked me what I thought of her perfume. She kept saying “I wonder what people think when they see us. Maybe they think I'm your aunt or something.” and started calling herself “Auntie Dove.” (Dove is her nickname) One night, she randomly joked, “If you were 10 years older,” followed by a weird exaggerated moaning sound. But when we got back, she just went back to insulting my beard. She still said that she's jealous of my hair and that I “look like a hot woman from behind” though.

She once asked me for advice about another male friend making unwanted sexual advances, saying she wanted to cut him off and feared he might eventually assault her if she kept turning him down. But then later said that she didn't want to cut him off because he's a “nice guy” and “just being a dude”. Then later she called him a “sexual predator”.

She also worried that my mental health issues were caused by her. She once said it “concerns” her how much my life experiences mirror hers.

I feel like I'm getting mixed signals here or is it just be overreacting/overthinking this?

TL;DR: I (21M) have a 32F online friend I've known for years. We talk daily and met IRL once. She has a dark sense of humor, sometimes making extreme sexual jokes about me, but also throws random insults and dismisses them when questioned. She fixates on my age, saying I'm "too young" for serious talks, yet still opens up about heavy topics like suicidal thoughts and fears of sexual assault. She discourages me from dating older women while making weird comments about our own dynamic. She’s also inconsistent in how she views other relationships (e.g., calling a guy a “predator” but continuing to talk to him). I feel like I’m getting mixed signals—am I reading too much into this?
