I’ve been seeing a girl for over a year and now all of a sudden she’s stopped responding. I missed her text and call and an hour later texted her saying I’m working right now. She’s still not responsive. What can I do?

We’ve been seeing each other for over a year, went on an international trip together, and she’s been coming over few days a week to stay at my place.

Couple of days ago I missed some text and call and now she’s non responsive to my text and call. She’s read the messages but no response. I know probably the best decision is to just ignore it and keep moving since if she’s not interested in responding anymore then it is what it is. When I was with her, I felt like she wasn’t the right fit for me but now that she’s not responding I’m really missing her. I can go visit her at work to see what’s up but I know that’s not what I should be doing. I sent some funny texts last night saying I want her here and that I’m sorry with emoji, etc.

What can I do at this point? Just keep moving with the attitude that if she wants me then she’ll respond if not then the last 1.5 years is just thrown away?
