Getting back to the path of a committed couple

Lots of marriages and other kinds of long-term relationships find themselves strained through a language barrier. It's not the common language that's the problem, though, but the way a sentimental person's mind is so different at analyzing things when compared to a logical person and vice-versa.

As problems accumulate while living together, stress and fights start winning the race of how to (not) solve an issue. This situation might show itself in the little things as they're aggravated, or blow up in something that should be big but becomes overly extrapolated. No matter how it happens, it gets uglier and uglier over time.

Even if a couple tries to talk about it, a conversation doesn't flow naturally. Trying to get logic out of a feeler doesn't work, but trying to put a logic person in someone else's shoes using analogies won't get very far either. So, how do we fix it? Where can we find common ground to make a deprecating relationship work again?
