My eXN loves her new victim

Ok so its been 4 weeks since i got my ex out of the picute. I have posted the background on My Story forum..

Yesterday my exN contacted me as I was ignoring her. I was told I was being pathetic and immature... This was after flashing her new partner on FB for me to see and then asking me to be a refernece for her... She told me she loves him and gives him more appreciation than she ever gave me in 18-months...

This was after asking me for sex and other things over the last 3-4weeks which she denies. I am at a place where I a glad she is out of my life, but the pain is real... I have envoked NC, but how can she love him after 3-weeks???
