What if the "Love-of your-life" is very much attached to another?

Saturday Dinah a close friend insisted that I go meet the "love of her life". She wanted my opinion on him. OK .... alarm bells should start ringing at this request. Anyway I was curious so I obliged, plus she has always been there for me. Last month when I forgot my wallet & documents, she's the one who took a cab all the way across town to rescue me: when it rains, we share her umbrella, so..... I owe it to her.

We met at this place we frequent for drinks. The Love-of-her-life came, 'I should have guess', it turns out I do know him... like for a long long time! No wonder she insisted I see him. But why can't she just tell me , who she has been dating for the last week? YES they have only been dating ONE week.

As it turn out there's one tiny hiccup: Love-of-her-life aka Tyler has a girlfriend. It's one of those relationships with a duration that qualifies for common-law marriage. I'm quite sure they owned a joint account together, probably pets too. I've seen them eating the same ice-cream cone back when we were in the university. And I saw her in his car just last week zooming pass my place. Ya, not only were we school mates, he's almost considered my neighbor. He lived like a stone throw away from me. I know most of his siblings as well!

The odd thing was, he started grinning at me as if nothing was wrong. As I was about to ask him, point blank how's his other girl friend, his cell rang & he excused himself to answer the call ,(whose most probably from his other girl )I got hold of Dinah & told her about the 'truth'. She looked at me in the eye & said she knew.
WHAT ??? !!!
Tyler had told her he's trying to break it off with 'that girl' . Since he met Dinah (ONE WEEK ago, he knew she's the ONE ) Oh..ya...sure....
What can I say, I can't smash her head with a bottle or a bat, to wake her up, can I???
I sure wanted to ....
