XP and I split up about 4 months ago. He got together with someone else not long after and I've learnt today they have gone off on a two week holiday to a place where we always discussed going but could never afford. I know I'm being unreasonable (which is why I haven't put it in AIBU) but I am feeling so jealous - firstly because he has moved on so quickly and I haven't, secondly because he's taken her on holiday and lastly because he has a narc personality but I hear he is being on his best behaviour with new GF and being kind, considerate etc which he never was with me.
I really hope Karma works and she finds out what a dick he is and dumps him. I'm aware this doesn't make me sound like a nice human being but please don't flame me.
Do any of you believe in Karma and have you seen it in action?
