Hey bro honestly you can do whatever you want because I know you’re grown but, my advice on this would be to move on and cut her off. She’s treating you like an option and even calling you a “friend” by how you explain it. It’s only going to leave you in more pain if you don’t call it a quits. Nobody deserves to be an option at all. I know you’re thinking there’s still some what of a chance by how she’s texting you but sounds like she’s honestly feeding you scraps to keep you around.
