Ever felt this way?
This is not necessarily about a wrong 'love' choice. Perhaps a job choice? A relocation? Or another decision you've made. Bad choice? OR, maybe it seemed wrong, but turned out to be the 'right' one for you.
I've made those choices. Some were bad for me. A marriage, for instance. OTOH Another marriage choice was right. BTW: I have BTDT re: the song. Gah! Love is...difficult to define, explain, et al.
What choices have you made that were good? Bad? Good at the time? Later, not so good.
