To Major

From now on, my no means "no" and you will respect it as such. 

When I am not playing with you, when we are going about our everyday life, I do not have to say red to mean stop. When I say stop or no, you will stop. 

When I say stop, do not push as far as you can without doing the thing I just said no to. This is unacceptable, it is not funny, and it causes me to distrust you. 

This has happened more than once. I am not just referring to the most recent time when I told you not to touch me, and you purposely moved into my space. If you expected me to step back and give, you were wrong. This is not a game, I am not playing, and you manipulating me based on my personality is not going to happen again. 

1) this only happens when my husband is not home.  (So I feel isolated and am unlikely to say anything)

2) you push up to the line enough to make me angry and uncomfortable, but not enough to feel like I can say anything.  (You know I avoid confrontation and don't like to make waves)

3) you play it off as a joke so that I wonder if I'm overreacting. (I always question everything when it comes to standing up for myself, and I'm more likely to let it go than say anything) 

We have not played since before January, and until a decision has been made as to whether I will play with you again, and when that will be, I do not want to be flirted with or touched without my permission. 

Edit: 

I am standing up for myself. I do want to have a conversation about "why"  - but every time I told you no before, if I told you "why" you used it as a way to tell me I was wrong, to say that my reasons weren't good enough. They don't have to be good enough for you. So I have only told you no lately and not given you that opportunity to undermine my answer. 

When you are ready to listen and not try to slip past my decision to get what you want, we can talk about it.
