Holy crap, this thread took an interesting turn.
Hehe... anyhow, I do feel a lot better this morning. I think the key is
time. Life is a long, long ride, don't rush anything and make hasty decisions. The break-up was a well thought-out process. Now that I'm past it I should take just as much time/effort to consider any doubts I have.
*sigh*
That, and to stop drinking in some feeble attempt to replace the emotional cloud with a drunken haze. That would probably help a little bit too.
