“A lot of relationships can change, but some will not – that is the bad news. Your decision may be that closing a door makes more sense to you than always having to knock on it to see if your passive-aggressive spouse is in or out. Leaving, sometimes, is your only solution. If, over the years, most of your energy is expended on short-lived and essentially ineffective repairs to the relationship, rather than living the relationship with its pleasures and pains, it may be time to get out.
“At a certain point, you have to recognize that your interests will be trampled on. If your relationship is about how-your-relationship-doesn’t-work, and you see no improvement, then your healthiest move may be to end it. You are entitled to more, and if the passive-aggressive in your life cannot or will not give it, seek your happiness elsewhere. Again, it means sizing up the situation realistically – knowing what he does and does not give to the relationship, assessing the real value of his promises to change.”
