Would you wait 6 months for your lover to come home?
"Love" or "Lover"? There are two very different meanings in those words.
Really, if you love this person, six months would be nothing. Are you really that shallow to wonder if six months isn't worth the wait for the person you love? You can't keep it in your pants for six months? I'd say, if you even have to ask this question, you should just dump the person now and save the heart ache of the "Dear John" letter later.
