It is difficult to say what drives people, and I am one of those people who rarely verbally expresses love, love can be easier expressed verbally by some than others. The problem is the depth and type of love one is expressing, and to whom they are expressing it. I have had females friends whom I actually loved as friends but dare not verbalize it, it can be / sometimes is, easily misconstrued as something else. When signing a correspondence I generally send the party I am addressing wishes of love / peace/ health/ happiness, but is generally as far as I go, though being an older bachelor, I probably am safe, but I am careful. In general, it would depend on the individual, as people express love in many different ways.
