Hope this is okay to respond but as a father to an adult daughter I have thought about this a lot. Our daughter is married, empathetic, and simply a nice person (also a productive member of society) and I think some of that has to do with how I made a concerted effort to make sure my relationship with her mother (my wife) was healthy. I treated my wife how I wanted my daughter to be treated, with respect, dignity, love, kindness, humor. All of those ways we want to be treated ourselves.
It wasn't all roses though for sure. Sometimes it was hard and we fought like normal couples do and all that but we worked to get on the other side of those times. I made (wife did too) an effort to not carry contempt toward one another for too long. Limit the smart ass comments. No name calling ever. Try not to let contempt be in the tone of our voicees when we were fighting. We had or developed over time some ground rules for our marriage that engendered respect even when we were pissed or hurt and stuff. I think ensuring our kids saw that people can be humble, admit wrong, apologize, and then move on trying to be better sinks in.
It seems perhaps corny and maybe weird but I stuck with it and she grew up to be a great person. Sure she's got her flaws and her challenges but she is a really good person at heart, and has a great relationship with her husband and with us. She's tender toward animals and and toward genuine people and, maybe most importantly, she doesn't play the victim. It's neat to see. I like to think some of that is because I worked hard to be a good father figure. But I the eve of mother's day in the US it's also important to admit that her mom played a critical role as well.
So congrats on being a father. Yes, it is a weird and magical bond between my daughter and I. I think what she was looking for in her committed relationships was rooted in how her mom and I communicated and how she witnessed our relationship as she grew up.
It sounds more formal than I suppose it really was I think. But, a few things were kind of baseline assumptions we worked from. No name calling or snide insults in a hurtful manner. That seemed to be a really core value. We allowed apologies when they were needed after an argument and we allowed them without any eye rolling or derision. We tried to go to bed without contempt...certainly we could be irritated, maybe angry but that didn't mean we didn't like each other so it was a sort of neutral ground, in a way?
Trying to explain it seems so contrived and cringe but in my head, and believe in hers as well, we had some idea from our parents what we should try to avoid and that was our starting point. Our parents provided a model of what not to have in a marriage and so we talked a lot about that, especially when we first met.
Also, no TV in the bedroom. Ever.
These are still the set of guidelines we follow now. Even without the pressure of children.
