Hi @Woman30 .... I'm back ... finally ....
Two things I have learned are these -
Sometimes we simply don't think to ask to be included. If it's something we naturally expected, then when it doesn't happen, like being included in the decision-making, then we feel excluded and from that mind-set we can forget that it's okay to speak up, and simply ask. That doesn't have to be a serious discussion.
It can be something like, "Can we talk about it before we make a final decision ? Two heads are sometimes better than one ...."
Or "Would you mind sharing with me how you came to that decision please ? I would like more understanding about it."
You are quietly and calmly affirming that you are an intelligent woman and expect that courtesy. Your son will hear your manner and expectation and will learn that you are standing up for yourself. This is something to be respected, and he will l arm that.
The second thing I have learned is that politeness is very powerful. It says many things. It is a request for respectful behaviour in return. It de,onstrates that you are respectful yourself. Your son will respond to this progressively.
Politeness also becomes a privacy shield. People have to over-ride respectability to reach beyond a barrier of politeness. For instance, if someone asks how you are, and you respond with, "I am very well, thank you." Even if they suspect that you are not well within yourself, they can't exactly say, "I don't believe you are very well. Tell me what is wrong." So using politeness, you get to control your boundaries, and if people around you are not respecting them, quietly and firmly keep repeating what you said politely in the first place ... "Yes, I am very well, thank you."
I hope this helps you within your home situation, particularly if your husband is very controlling. Mine, through illness, has become very controlling, so it is something I am struggling to contain. The advice I have just offered you is what I apply to my own situation, but it doesn't always work easily, and it takes practice.
Take care,
F&H
