Keep delaying why?

My fiance and I have been together since December 2016. We got engaged in February 2020. Before we got engaged we knew we were going to get married just hadn't made it official yet and I had all sorts of ideas. Now that it's real I just don't feel like making any plans. He wants to get married next year I said why not make it 2022. I don't know if it's just I don't feel there's any hurry... We are in our 40s, we already have kids from previous marriages, We already live together We don't need each other's insurance. And then to add to that when I do try to talk about wedding planning I get shut down by my mother who feels I already had a wedding and I don't deserve another one and should just go to the JOP and keep it under the radar. we're paying for this wedding ourselves so it's not like we're asking anyone to financially contribute. We want it to be a big celebration of family and getting a second chance at love with the people closest to us. I just can't get myself to make any kind of set plans like talking to photographers or caterers or musicians or anything like that. I make vague plans of trying on dresses but That's about it. The other thing is that he has a daughter that we haven't seen in over a year because her mother has kept her from us...she lives in another state... and she was supposed to be in the wedding. We had talked about it before we had gotten engaged and I think part of me is holding out hoping that she will come back into our lives. Let me know your thoughts.
