Relationships

Friends or more?

So I got a new work partner at work and she is the coolest chick i know, she listens to a lot of the same shit I listen to, she likes the same movies and she is single and I'm about 6 months out of a 22year long relationship so I haven't really had to try hitting on any females because I was content with the one I had.
I am trying to hurry and save money for a car because the last one I paid half for but let the ex put ot in her name and she blackmailed me.
Anyway I left her but wasn't reL serious about it and she kept wanting to get together and so when I said okay she said no we can't and she had a boyfriend.
Anyway this partner of mine at work picks me up every 4 morning and takes me home, which she also gives a couple other people rides to sometimes but like I automatically get shotgun in her car and she jokes around with others like how good her partner is and stuff.
I wanted a car because that would boost my confidence, I did tell her I'll buy if she wants to go have Chinese buffet or something because she said she likes it and she replied okay and didn't seem to interested, what do y'all think I should do? O also have the ex saying she want to come back but I don't want her back because she a horrible person.
Friends or more?
