TL Maybe it is because of the tone of the words being typed as opposed to the words being said but it seems to me, simply reading the words on the page that you are....well...just there. And that by being there, you get to say you upheld your commitment.
To me, this isn't upholding your commitment.
The commitment you took was to love and honor, to cherish your partner. As she isn't a partner and you don't look at her as one, you are not honoring that commitment. You are simply stubborn.
It seems like there is a message you are sending your children that just doesn't jive right about relationships and love and commitment
