"romance that has ended and left some one a bit miffed"
And The Understatement of the Week Award goes to......

Holy cripes man... Your protagonist starts off by saying "He'd" rather be lied to.... Then "He" states that if "He" had "His" way "He'd" hypnotize "Her" and MAKE "her" stay against "Her" will..... Later "He" suggests that it might be o.k. with "Him" to KILL "Her"....

Then "He" belittles "Her" wedding day.....

Then in a fit of pique "He" runs off to drown "His" sorrows in beer all the while wishing ill on the people who don't understand "Him"....

It's no wonder "He's" alone....
