Dating issues 😭

So I've been talking to this guy on and off for about 2 years, we seemed to be getting serious closer to Thanksgiving when I spend the holiday with his family but now I'm not feeling the same vibes. Literally weeks later, now on Christmas break. We've never titled what we have and I'm starting to worry that giving him this freedom of "No Titles" was a mistake. It seems as if we're going in circles and the crazy part is... I think I'm falling for him! Any suggestions....
