Hey JJ, wanted to check in and say I'm keeping updated with your thread.
You're right, mentally I think you and I are going through the same phase. We're getting to the point they reached, and then they gave up and left. Leaving us alone and we made the changes. I keep telling myself that I however have different tools and understanding than our spouses did and I know better than to have expectations and then just throw in the towel when things don't work exactly how or when I want them to. So do you.
That said, it's still gets damn old doesn't it. Sometimes I feel like the parent talking to a child with no concept of understanding all this. They're still learning. Just like we did.
But when do you give up, draw the boundries, say I'm not being cheated on anymore. This is not the life I want to live. I tried.
