What should I do?

I’ve been seeing this girl for a few months now. The first month she lived pretty close to me, but now she lives about 4 hours from me. I’ve driven to her a few times and I wouldn’t mind continuing to. I think I do have anxious attachment and have felt recently that she doesn’t really like me as much I like her.

We’re not official, but have talked about it, the last time I went to visit her, I told her that I loved her as I was dropping her off and leaving, she replied with “really?” And I said yes, but she didn’t say it back. Then as I was driving away, she texted that she loved me back.

And I get the feeling that I’m not a big priority for her, cause she doesn’t text often and I’m usually the one trying to either play games with her or watch a movie. I also told her to get a headset so we can talk, and she said she would but she hasn’t.

I’m thinking of pulling back and not really initiating for a couple days, or telling her how I feel and ask her if she actually likes me. Because I was gonna ask her to be my girlfriend next time I see her. Which should I do?
