Relationship anxiety

Hello all, I have been going out with him for about 5 months now, And I do believe that I am in love with him. But for some reason I feel this sense of anxiety when I think about him.. This could be because I was married to my ex husband after only being together for two months... I don't know our work schedule are completely opposite and I don't see him but on the weekends... Am I just over thinking things because I'm worried about being in a committed relationship again...... I know that I am all over the place with my thoughts, this just goes to show how muddled my mind is.....
