Am I being strung along

I’ve been talking to this girl for going on four months now and I feel like I’m being led on. The last few months talking to this girl have been amazing, we’ve been talking on the phone for all night at least once a week. Although I love talking to this girl every time I ask her to hang out she says she’s busy. She just started working full time and just started her summer class, but I feel like she might be leading me on to believing she wants something more.

A little background we went to highschool together but never talked back then we’ve recently connected due to online dating apps, and I really like talking to her. I’ve never felt this much enjoyment in talking from a phone call. I haven’t dated in a while and felt like I finally found someone that I like enough to take another chance with. But after quarantine ended I’ve been asking her if she wants to hang out at least once a week. I keep getting “I’ll let you know” but she never does. I don’t want to end this too early because maybe she is busy and I don’t want to back out too soon just in case this is something special. I really like this girl but I’m afraid she’s leading me on. She makes time for all her friends to hang out with her. But every time I ask she says she’s just got a lot going on, which I get, but that she always gets busy last minute. I’m genuinely worried she doesn’t want to hang out yet we talk everyday. Even when I try and bring up the fact that we haven’t hung out she still hit me back up which makes me think that there’s a chance we’ll eventually hang out. Am I being led on? Should I end this? I’m going back and forth on ending it and giving her a chance and it’s stressing me out but I don’t want to end it too soon and miss out on something that could be amazing. What do you guys think?
