Sharing Our Innermost Thoughts

So this person I have liked for quite some time now very passively not ever thinking outloudly about him texted me yesterday. We talked for sometime , then he left me hanging for many hours. Then we talked for sometime at night and then again a little bit in the morning but since then he hasn’t texted me it’s been over 10 hours and it’s making me anxious I know it’s not that big a issue . I tend to overthink . It’s been long that someone paid attention to me.
