Emotionless Mother

Hi everyone, I'm new here! I'll be honest, I don't necessarily turn to discussion forums when I am struggling with something in my life. I usually find a way to work it out on my own. However, I thought there might be someone here who could relate to me and make me not feel so alone. I got engaged over the weekend, and was absolutely thrilled. I've found a great guy who my parents love and we all get along with his family, it's really great!

When I told my parents we were engaged, they seemed really excited! When my mother asked what date we were thinking of, I was so excited to tell her we were thinking October of next year on my grandpa's birthday. It worked out perfectly because it was a Friday. Her response was, "That's when your Aunt and Uncle got married." That Aunt and Uncle no longer get along, and are thinking of divorcing. She further went on to say, "That's really soon, we were thinking you two would wait until 2021. That's just really quick, it's less than a year away." So that kind of spoiled the moment of telling them I was engaged. I ended up feeling really upset, and she then was backtracking telling me that it was fine, she was just processing. She then told me she's "just not an emotional person." Only a few minutes later she told us she was going to bed while my dad helped look at venues with my fiancé and myself. The following day, she sent me a few ideas of venues and was asking what kind of theme I would like, and wanted to tell her friends I got engaged, etc. Once I got out of work, my parents and I were talking and my mom was saying how she wanted us to have specific things at our wedding, such as a sit down dinner instead of a buffet. Her reasons for it were understandable, and I'm happy to look into it, but it can be quite more expensive than a buffet. My fiancé and I are planning on paying for pretty much everything ourselves, so it was a bit irking to hear that she "required" it. After that, we started looking at venues again and she looked at one with my father and me, but after that she turned the TV on. Today, I tried to have another conversation with her about a venue and she basically shut the conversation down. I'm dreading dress shopping with her because when I showed her the dress I liked, she only had negative things to say about it first before she finally said, "It is very beautiful." Maybe I'm being a bit sensitive, but has anyone else had to go through something like this? I would just like a bit more support and excitement from her instead of her saying, "I'm not a very emotional person." She's very excited to make her move to Florida, but not about our wedding...
