However, loving yourself enough to not allow yourself to continue to be mistreated, is important.
It also isn't saying that you don't love your H.
I love my X still. And I always will. My S is well aware of that. However, the dynamics of the R were not healthy for any of us. He is also aware of that.
While lessons about commitment are very important for children to learn, there are many ways to teach that. You not only have a commitment to your M, you also have a commitment to yourself.
As has been said a lot on your thread already, and is said a lot all over these boards, children are much more aware of things that we would sometimes like to think.
I have to wonder what lessons your children are learning about how to treat people by watching your R. What is your D learning about how she should expect to be treated.
We are not living in the beginning half of the last century anymore where women were a subculture and men could do anything they wanted and we just had to accept it. As our lot in life.
In countries around the globe where those sorts of cultures still exist, women are fighting to change it. Fighting to be treated as equal human beings.
Please try to consider all of those things when making your choices.
Standing up for yourself now, in no way says you don't love your H and in no way says that you can't forgive him, and in no way says that if things are different that being together isn't possible.
"Acceptance doesn't mean resignation. It means understanding that something is what it is and there's got to be a way through it."--Michael J. Fox
