Never allow your woman to question her place in your heart.

Allowing such questions to arise only provokes further questions.
Those questions tend to cause a raised eyebrow in your direction.
It will make her question what you say; what you say about how you feel, about your intentions & everything that you’ve ever told her.
She will begin to look at you sideways, and then it’s just a matter of time before she begins looking in the other direction.
Oh, don’t worry, you’ll probably still be around for a while, but if you’re in the east she’s probably be looking west.
Men and Women and completely different people, point blank, period!
A woman’s mind is complex; a majority of the things we say are deliberate and well thought out from several different angles before the word even leave our lips.
The same is true for the things you say; when they leave your lips they don’t go in one ear and out the other. They are stored, and re-visited, de-constructed and reconstructed in search of the hidden meanings.
So when you say something and know that you didn’t mean it or you said it out of anger and spite, apologize until the cows come home, but it stays with her. She doesn’t forget it, the hurt doesn’t disappear one day and its back to the way it was. She might put it to the side but it’s still there.
I can’t stress the power of words, kind word or harsh words, at the end of the day they are all WORDS.
Consider this, if you say vicious things and later take them back and say I didn’t mean it the question then becomes if you can say so much and mean so little, then how is she to believe the "I love you" and the "You mean so much to me" or better yet, the "I want to spend the rest of my life with you"?
Complex minds process complex thoughts.
Remember that; the next time you speak, stop in mid sentence if need be, and consider your words & how they will be interpreted.
Words have POWER!
