Is the relationship over or is this my rocd

Hi everyone, looking for some perspective on a shift in a relationship I’ve been in for about 4 months. Things were going great—we even had a nice Valentine’s Day—but the last two weeks have become difficult.

We had plans for a date at my place (I'm in Bed-Stuy, she's in Far Rockaway). She canceled a few hours prior with a long explanation about the stress of her recent move and getting her kids settled in school. I told her it was no problem. We kept in touch over the next few days, but then communication went quiet over the weekend.

On Monday, I texted her saying not to worry about meeting this week and that we’d plan something later. She replied warmly, saying she’d been thinking of me and wondering why she hadn't heard from me. However, when I followed up to see if she was free for a call, she didn't respond. The next day, my call went straight to voicemail. over?
