unfortunately people still hold feelings for their ex's way after the realtionship is over sometimes its hatrid yet sometimes its still a form of love. nothings changed from before if she is still talking about you to your mates, then she will still be clingy even if it takes a little while to show again. You've had no one since that has stuck around for one reason or another so therfore no one to replace the feelings you once held for her. You never truely get over an ex as much as your going to until you fall for someone else but you very rarely forget an ex either. Just be grateful you can still talk after all your history but i wouldnt reccommend going there again x
