Yes, I have the feeling I was only a rebound. He lied to me about how long ago his last relationship was. Especially towards the end he even wanted to give me a dress from his ex. I told him I'd rather burn in hell. I felt like in Hitchcock's Vertigo.
If I had known that he was still in touch with her one month earlier I would never have started anything.

Yesterday i had a great chat with another guy on my wall. We have the same passion and it was amicable but enthusiastic. The next day my ex didn't go on facebook the whole evening. The next day I noticed on his wall a pic saying "Eat me" (pun in a restaurant but with intended sexual connotation). It's not his style. His mum is in his contacts. And since that's how he communicates, I conclude that he is pissed.
Good. Now he knows how it feels.
I don't give a rat's *** if he stalks me. He hardly publishes anything so I'm not that tempted. It's probably driving him crazy more than me. But still.
