I don't know how but I came across this interesting blog with some interesting thoughts. And I totally agree with that.
My dad giving his response to my concerns was such a moment for me. With a knowing smile he said, "Seth, you're being totally selfish. So I'm going to make this really simple: marriage isn't for you. You don't marry to make yourself happy, you marry to make someone else happy. More than that, your marriage isn't for yourself, you're marrying for a family. Not just for the in-laws and all of that nonsense, but for your future children. Who do you want to help you raise them? Who do you want to influence them? Marriage isn't for you. It's not about you. Marriage is about the person you married."
