My wife is pregant and has been leaving me out! 😞

Recently married and we have our first baby together on the way. I already have two 17 and 12. We both wanted more children. We choose a donor together and said we were both going to use the same donor for the next two. I decided to wait because We wanted to make sure she would be able to get Pregnant and I already had two. My issue is. Through this process of Insemination and her getting pregnant she and her family have excluded me out of so many things. Everyone has made me feel like I’m not a part of this. And I am tired of trying to speak up for myself so I just stopped saying anything and stopped going around her family. (It seems worse when we’re around them) I have still been there for her and everything she needed. Everything she asks for I give her. She is now 7 months pregnant and she has recently started including me in things. But now I’m scared that if I say something wrong or disagree with her family I’m going to go right back to being on the outskirts of everything. I have tried to communicate so many times!! Ugh. I’m frustrated. And I don’t know if I can handle it. I feel like I’m going to snap!! Because of how I have been treated I have procrastinated on doing the process myself. But I still want to have another. I feel like I have procrastinated long enough. So I have an appointment in October with the doctor to see my options because of my age. (44) I’m keeping my fingers crossed about getting pregnant.
