obsessed ex boyfriend 

a lonely loser creep who writes definitions on urban dictionary to vent about a woman who left him. Makes it look like he dumped her when the truth is she left him a long time ago after she realized what a broke bum he was. Has now developed a sick obsession and cant let go of the fact she dosent want him anymore. This guy thinks he was in a relationship with this person but the truth is it was nothing at all and she felt sorry for him.

Never befriend a pathetic loser, he'll start thinking your his 'girlfriend' and become an ''obsessed ex boyfriend''
She never loved you, get it through your thick head.
Stop wastin your time and move on
