Tlrd: wha5s signs do I look for flirting vs friendly?

So back story, antidepressants were started 2 weeks ago there going good. I like being happy and not stressed.
I'm a very impulsive person cuz adhd. Adderall and wellbutrin help a ton.

Met this girl on Saturday got her number from her cousin on Sunday. Talked all Sunday resisted the erg to impulsive text her, said happy birthday at midnight and had a brief convo about school.

Today asked how her bday went then were texting and I mentioned how I really want to go for a drive and ask her if shes ever just has driven to drive. She said no she hadn't so I tell her how much fun it is and she says that sound like fun. I replied with okay, I'll leave in 5 to come get you. Her response was "what" I told her you said it sound like fun so I'll come get you. She said okay and I asked for her adress and we drove for two hours.

She talked I talked. Most the time when she said something bad about her self or how it's strange I replied with how it's not I actually enjoy those things and that I think there cute. We had good banter and I enjoyed it. Conversation died around 145ish a d she said she should probably be getting home. So I took her home. She said bye and see you Thursday ( the orginal day we were supposed to be alone without the group. Cuz we met Saturday) idk she seemed to enjoy it

She recently just got out of a year long relationship. She commented on it once never brought it up again. I know well probably just be friends but what should I look for if someone is flirting? Honestly it fits over my head.
