More than friends? (advice please 💕)

So I've been kind of confused lately... I'm currently going into my third year of highschool and have been getting some mixed feelings about my guy-best-friend. We hang out a lot (almost every other week) and text every day. We have even dated in the past (but it never went anywhere).... and have been mutual friends for almost 2 years.

Anyway, we both noticed that we act more like a couple when we're 'just friends'..

Recently he has been getting really "touchy-feely" with me whenever we hang out (ex: playing with my hair, snapping my bra, tickling me, picking me up, etc.) and has joked about touching my butt/boobs because I have 'the perfect body' 😂

Also, he has been making the most sexual and inappropriate jokes about me

(sometimes including himself)...he never ever used to be like this. It's like his humor went from innocent to dirty over the summer.

-- I brush off his comments because I'm not offended and honestly think it's kinda funny, even if it's a little uncomfortable.. it just makes me wonder....

Do you think he wants to be more than friends, or is just teasing/messing with me?
