Many have said a couple is meant to function as a unit, with one partner supplying what the other lacks. In other words, a husband and wife are to complement each other - complement, not compliment (although a compliment now and then would be nice) - to supply the skills the other needs in life. What do you think you lack that a spouse might supply?
I haven't heard of this explanation, so it is new to me. I mean, I know that a husband and wife are each other's best companions, soulmates, better halves, etc., but I haven't heard that they are to complement each other. To me, that comes across as being dependent on my partner to complete me and that seems to be complacent thinking, whereas, I would depend on my partner to guide me when I fall short because I want to work towards perfection myself.
Anyways, these are the areas where I fall short -
1) I find it hard to say NO to people who are close to me (that is something I am working on, right now)
2) It is hard for me to keep aside my feelings whenever I am analyzing an issue (ENFJ personality, yo)
3) I tend to overthink and over-complicate even small things because that is how I think (ENFJ, again)
