Just friends or potential crush? *read description*

I have recently been meeting up with a guy I have known since school. (We are both 21 now)

I normally get my dope off of him so we have spoken since school etc.

I told him I split with my ex and I asked if he was still with his GF and he told me they broke up 7 months ago.

Since then he started putting a kiss on the end of his texts which he has never done before and he isn’t speaking to me in slang anymore🤷‍♀️ this is when I first asked if he wanted to go for a smoke to which he replied saying he would love too.

So we have met a few times for a smoke and I’m starting to get crush like feelings for him.

I’m not sure if he likes me back and it’s been me arranging the meet ups (approx 4 times so far) and he always seems happy to meet up with me.

We have really gotten on well when we meet up, both laughing a lot and having big heart to hearts, to me it feels like sparks are flying with chemistry there too? I started giving him a hug when we say bye and he always says ‘text me’ yet he takes 6+ hours to reply. He works full time and does the dealing on the side.

Are we just friends? Does he potentially like me? Or should we just keep hanging out until things become more clear?
