I'm posting in AIBU as I really need an online arse kicking. ExP, who I couldn't stand to even have a conversation with due to his narcssist personality, has a new partner. I don't WANT this man, I was the one who ended things but... I am so jealous! Like stomach churning, can't stop thinking about it type jealousy. We share a child together so I can't go full NC. I don't have him on any social media. We communicate only for our daughter. And these feelings are crippling me. What the hell is wrong with me? I'm not even sitting thinking about all the good times and changing my view of our relationship, I know he was a prick to me. Anyone ever felt like this? And any tips how to get through it and feel indifferent towards him again? I'm actually devastated with myself for feeling like this.
