I'm no expert on relationships or matchmaking but I don't think I made many mistakes when I chose my partner. She was good for me and to me. Of course there were little annoyances but that comes with the territory.
That being said, I was a different person then and I wouldn't make the same choice today, nor would I have made a similar choice nearly 20 years ago (or all that time in-between) after she died.
This was always a rub over on the other board in the Singles section. Between the fat chics that posted there and the super large Admin that overlooked it. My wife died as a direct result from a lifetime of bad eating habits. I've outlived her now nearly 20 years and I drink and smoke, which she did not. I would not choose another partner that abused her body with food like she did. Call it shallow. I call it experience. A very hurtful one.
