Am i too insecure?

I am with a great guy. This is a guy that I really want to see things work out with more than I ever have before. But I've been catching myself becoming a paranoid twit now! I worry every day that he's going to leave me, that he's going to get bored,...

that he'll find something better, and so on. He's done nothing but reassure me that he loves me, and that he wants to spend the rest of our lives together. I guess I've known so many guys who would lie...that I don't trust this is true. But again, his actions when he's with me say he does care. How do I find a way to feel more confident here without asking him to jump through hoops he shouldn't have to?

I think its normal all females tend to be that way sometimes I myself am the same way but in time it will get better but you have to find your confidence.
