Needs advice BADDD😳

So me and this girl have been having a “thing” for a year now... We weren’t technically dating... but I guess you can call it a situation. She has been the only girl I’ve slept with and still has been now, but I think I have feelings for her. When I think of me being in a relationship rn I see me and her together.... she’s a horrible texter with everyone and we mainly text now for hookups. But I feel like she’s still heartbroken and stuck on her ex & still has hella trust issues:( what should I do.... should I tell her how I feel... or wait to see if she shows me she wants something more than sex. Or should I cut her off?? Thanks 🥺
