We broke up a few months ago. I dumped him as he wasn't listening to my demands and our lack of communication in addressing arguments grew rapidly.
Anyway, he had moved with me to France as I'm French and we were both studying at the same university (he was already living there before-thats how we started dating). After our break up, I asked him to leave my place and he left. After a week he went back to Copenhagen (as he's a Danish national) and then I heard that he suddenly flew to London (we studied in UK/London for university).
Turns out, he went there to meet our mutual friends and then he met his almost "ex girlfriend" whom he was in love with and had fallen out with before they could date. It was his fall out with her that he decided to leave London and move to my country and it was him being jilted over her that he quickly latched on to me as we were talking too much.
This "ex" is apparently the girl he was in love with from first sight and "whom he could never get out of his hear as she was his one that got away". My friend also said he had deep regrets over leaving her and wanted to talk to her even when he was dating me.
That desperate girl also "loved" him and then I found out that he became her flatmate (as she was living in a short term hostel accommodation) and he gave her the 2nd room in the 2 bedroom apartment he was renting. Now, they are together in a relationship, and the girl has uploaded pictures of them on Facebook as featured where he's holding hands with her in every single one of them (something we rarely did unless we were mushy). Our friend also told me that the way he looks at her is something that can't be explained. Never did that with me either.
I dont get it. Why is he doing this? He left her and was with me for 2 years, we were friends with each others parents, siblings and then he claims he never lost feelings for this desperate girl ?
