Absolutely 100% correct. Take care of yourself first. "I want us to stay family?. WTF...over? What color is the sky in her world. Probably drank from the same Kool Aid snifter as my W. I'll say it again, just as I alwyas do. I signed up for better or worse...not "if I'm not satisfied" or "if you don't work as hard as I do at the marriage" or one of a million reasons they have to use as a lens to do what they're doing. I was not happy either, but I would never do this to my family. If we had to live as brother and sister I was OK with that. We had no sex for three years. I wasn't happy or "satisfied", but didn't look elsewhere. Life IS NOT fair, my friend.
My FIL sent me pictures of my kids rom Thanksgiving, along with some of them as little kids. It ripped my heart out. How can it not do the same to them? It will be three years when I get home that she told me she wanted out. It's gotten easier, but the feelings when I saw those pictures was like someone poured salt into an open wound.
