I want to talk about 'learning to understand "who-your-wife" is as a person.'
Know that she is a daughter and sister and niece and granddaughter of someone else. Never forget this fact.
Know that she has different build from you. Totally different, okay. Check out the anatomy text book, in case you are not sure about it. I am talking about her feminine body structure i.e. from the DNA structure to the size of her bones, her monthly cycle included.
Know that her bodily structure influenced her emotional structure.
Know that her mood swing is greatly influenced by her bodily changes too.
Know that she has acute intuition and can tell what is happening even if you did not tell her. Most of the time, that is.
Know that there was a reason perhaps many reasons why she chose you to be her spouse. Get to know what was or were the reasons. 'Post-it' it in your head. Don't loose that particular information, if you are seriously serious about your relationship with her.
Know that you must never ever attempt to build a habit of 'lying'. If you do, you are digging your own grave. Good luck.
Know that a marital relationship is a serious business. As such, handle serious matter seriously. If you love, love seriously. Meaning, Love honestly, with good faith and with good intention. You do not want to be a hypocrite, do you?
Know yourself. In knowing her, you know yourself. Knowing who you are is learning to know her.
By taking the initiatives above, you are constantly awarding yourself with a peaceful prosperous and wonderful life. Because, you are the one, in the first place, who decides that you want to end your single life. So, make the effort. Be accounted for.
Well people, I have no formal education in psychology or counselling or anything similar to that All these information were experiences gathered over the years while interacting and participating with other human kinds who crossed my path. So, they were valid points, I supposed.
All the best! Continue building and constructing and loving, people.
