Wondering if my long-distance GF (23F) still loves me (23M)

My girlfriend of 3 years lives in another state after having to move away for grad school. I have always traveled to see her and text her regularly and attempt to communicate the best that I can.

However, recently we have been hitting rocky roads where she claims she doesn’t have as much time to speak to me. She even tried to break up with me within the last month because she felt I was too emotional but claims she loves me and made the decision to stay and has even flirted with me as recently as yesterday. She tells me she loves me every single day. But why don’t I believe her? Every evening, she is hanging out with her friends at school even if to study together but I know they’re not just studying the whole time. She will be at her friend’s house for many hours on end (sometimes more than 7 hours). Recently, she has been really only speaking to me about once a day in the evenings for about a 20 minute phone call. Usually past midnight.

I’ve mentioned to her that I feel my needs aren’t being met and she doesn’t seem to miss me or want to speak to me herself. She insists this isn’t true. Two days ago, I didn’t hear from her all day and night, not even a phone call that she instigated (I had to ask if she had time to call to say goodnight, she told me she would try to find time) as she was hanging out with her friends all day. She called me on her way to the bar and we spoke for less than 5 minutes with her other friends there too around midnight. It was the first time we had spoken all day. Pretty much had been almost 24 hours since we had the last conversation despite me reaching out multiple times. She recognized we hadn’t spoken much and apologized. But I have not heard from her today at all.

I have started to feel crazy and like I am overthinking everything. Maybe I am, I do have OCD and I overthink a lot. But a lot of my friends are asking me if I genuinely think this person still loves me, and I truly have no answer for them. It’s so hard because her actions and words don’t line up (IE, telling me she misses me but refusing to reach out to me and going all day without talking to me and comfortably doing so.) Am I being crazy for thinking this person does not miss me or love me? Or am I onto something?

TLDR : My long-distance gf of 3 years who is the same age as me barely speaks to me because she claims she doesn’t have time, yet also claims she still loves me and misses me while making plenty of time for her friends and things she wants to do.
