Watch Out for the Love Words

Apostate is an unusual word, but doesn't mean 'liar' or 'hypocrite'. It just means 'abandoner of one's own religion'. It seems the other person was insincere, but not particularly a believer; that he had feigned feelings.

I also think "but" at the beginning of S3 would work better than "because"

I very much like the placement of "shit" at the end of S2. It quickly removes any of the romantic feel that a lot of 'love-betrayed' poems sometimes carry. It jars us back to reality, to un-romantic honesty.
