If I think back on my own parents' marriage, that's about all I learned from them, too -- how to be roommate friendly. I couldn't tell you back then what their M pros and cons were. I couldn't tell you either one's LL, pet peeves, or who was right or wrong in a sitch. I didn't learn how to have sex, or how to date, or even particularly how to fight because you're not supposed to do that in front of kids. The rest of it I figured out on my own, either because it's what I personally wanted or from other relationship experiences. He's not going to learn the marriage lesson any better if his father and I are divorced. If we can't work things out when we both claim we want to, it will be a very conflictual divorce as well and there will be no caring left. It may or may not be the right decision for him, and we won't know until way down the line, but it is what I believe to be best. The years we spent in counseling with/for/because of my skids is not someplace I care to go if I can help it.
