Ginger - I know that you're concerned about being overly-critical - and you do have abandonment issues, so I get that.
On the other hand - this is early days, and dating is supposed to be the time when you find out exactly who a person is. Perhaps you are finding out he doesn't handle stress well, cannot maintain romance or speaking your love languages beyond the initial excitement phase, or simply isn't all you thought he was. Don't ignore red flags as they come up. And - what do you know about what happened in his past relationships? Try to see if he's repeating a pattern?
