beth........So nice to hear from another woman who is polar opposite from her husband, yet have a good relationship, despite this fact. My husband (now deceased) and I were this classification of couples. There were very few minor things we may have agreed upon. For the most part, considering all major aspects and concepts of life, we were simply complete opposites.
It could very well be that this works for some and others who can't imagine being in a relationship as opposites. My hubby and I often wondered about it ourselves. LOL......I think, actually, because we were asked so often by others HOW the hell we got along so well and remained so happy together, being as totally different from one another.
I'd have to say that it requires 2 mature, intelligent adults who respect one another as well as their viewpoints, goals, beliefs, etc.......and refuse to allow the differences to be a source of annoyance and/or debate.
I can assure any doubters.....it worked just fine for us. We had a very happy, comfortable relationship.......and a lot of laughter.
Relationships are as complex as the people who make up the relationship. If they want it to work, it will work...... GREAT question
As for WHICH is more often found to occur? I'd have to say 2 people more alike........rather than different. The latter is probably fairly rare!
