Loving someone is a choice, being in love is a different feeling. I love my husband, children, parents, siblings, friends, etc. I choose to love everyone, because everyone deserves to be loved. But I am in love with my husband, and he is the one I enjoy being with most.
On the other hand, coffee, well, I'll leave that alone. I do not like it and it smells like a skunk to me. So, I will not compare coffee and love, because they are so opposite to me. I enjoy being in love, but I will never enjoy coffee.
By the way, I've been married to my husband for almost 44 years, and we still have that spark! I hope you do, too, when you've been married as long as we have.
