Why am I so insecure?

I'm crazy about a guy I've been seeing for almost four months. I haven't been in a relationship in 5 years so I forget how they work. He spends at least three days a week with me but I'm always insecure he's losing interest or doesn't like me as much as I like him. I literally get panicked sometimes because I'm afraid I like him too much and it will scare him away. How do I get over this?

This isn't the first time I have felt this fear and it usually leads to them walking away. I just like him enough and he shows enough interest to keep it at bay. But when we part without future plans to do something later I get nervous about when he will want to see me again.
