My ex recently married. We have been apart for more than 2 years. We were together for three years and during most of that time, I thought we were deeply in love. We did have some unique challenges, not of out making, which I won't address at this time. Ultimately she found someone else on a dating site and left me. The devastation was awful but after much pain I am finally healing.

During our relationship we wrote many loving and romantic things to each other. At one point I wrote something from the heart. Not cliche. Not something anyone else has ever said. Just a few sentences that described my unique love for her. Recently I happened across a u-tube video of her marriage on the Internet. In it, there was a voice over of each spouse saying the vows they had written. My ex was saying, to her betrothed, the very words I had written. Simultaneously I felt heartbroken and somehow in a need of a shower. My question is: is this disordered behaviour or simply bad behaviour?
