I know my W was unhappy in our M. I have many regrets. I truly believe much of our unhappiness was situational. Three kids in four years, post partum depression, house renovation, financial difficulties, medical problems, all added up to stress on top of stress on top of stress. She seems genuinely happier in some ways, as she feels like she left the stress behind (which she hasn't, she just thinks she has, for now, reality will hit soon), but she has this "bad vibe" around her too, which I think is what you're referring to Sandi. She's obsessed with her looks and her weight. When her affair is on an upswing, she acts like she's in the world's best and most exciting relationship, she constantly boasts to her friends how great it and he is. When their R is on the rocks, she becomes mean and is a misery to be around, and our poor kids have to endure it. The ironic thing is that one of the "reasons" my W gave for why we needed to separate was that she thought our R wasn't a good example for the kids to see growing up. She felt we weren't loving enough to each other, which is weird for her to say when she constantly rejected my love. Anyway, what she's now living is a terrible example for our kids, in my opinion.
