Long story short, I just got married 2 weeks ago. He is a wonderful guy and this relationship seemed so perfect. We love each other so much and have planned a long and bright future together. Years ago, I found myself afraid of adopting a cat even I was longing for it so much. Every time I tried to reach out animal shelters, I felt enormous anxiety and gave up quickly. I didn't pay attention to my symptom then. I guess it didn't disappear after all. This kind of anxiety is exactly how I feel right now with my new husband. I feel trapped and suffocation whenever I think of my husband or knowing that we would spend entire life together. Additionally, I really feel my stomach pain when I think that the wedding reception is only weeks later from now.

Is this commitment issue? My husband and I are together for 3 years before we got married. Everything was good before marriage. Since moving in his apartment, the anxiety grows gradually. I hate myself wanting out. Not only I would potentially sabotage my happiness, but also it's so unfair to him.

Does anyone have the similar situation? Could anyone give me some advice?
Thanks!
