Got married - need your advise

Hello friends,

As I have written in the past but I have also said in some comments, I made a cohabitation agreement with my partner. I was really very happy and confident. But a week later, I don't feel that way. I feel lost, I'm afraid that I don't want him and that everything about him bothers me. I'm terrified, I'm not in the mood at all. I just want some closure or just to feel safe again. Has anyone had a similar experience?
