My fiance doesnt seem happy nor excited about our wedding

I honestly don't want to entertain negative feelings about my upcoming wedding since I know this won't lead to any good. But I am totally heartbroken right now after realizing how cold and unattentive my fiance is when it comes to our wedding.

We are in a long distance relationship and since we got engaged, we already talked about the things that will be arranged by him, and what are the things under my responsibility. However, up to this moment, he never started anything. And whenever I ask him for an update (for example a venue for our reception) that is only the time he will send me some pictures, or articles asking for my opinion. And after a day or two, nothing happens. There is only progress whenever I asked him.

I don't understand him. I want to understand what is going on with him, but I hate this feeling. I hate to see myself asking him all over again and doing the stuff because I got mad, and not because he inititated to.

I don't want any negative thinking or feeling but sometimes I feel betrayed. Because after all, I am not the one who initiated this wedding. He proposed to me and he is the one who wants to get married that 'soon.' I dont want to be pushy because I dont want to put pressure on him especially he is too busy at work but, the attitude is so annoying. I just dont understand. What should I do. 😒
