Emotion vs Logic = Heart vs Head. You cannot base your love life on one or the other. Trust me...that's been my problem my whole life. Using my damn head too much...and believing that emotion is not important and is a sign of weakness. Putting emotion on the back burner weakens the emotional part of you...and overworks the logical part. It would be like trying to strengthen your legs by hopping around on one foot all the time. Sure one leg would get really strong, but the other would get really weak. You're left with 2 mismatched limbs. Not good...
You need them both. If you act only with your head you'll over-think it and screw things up, if you act only out of emotion, you'll under-think and act rashly or too hastily and screw things up. As usual, the answer lies in the delicate balance, not one or the other.
Remember: When you're confronted by a dichotomy of extremes...the answer is right in the middle.
