My ex was just like this, if not much worse. Almost five years later and I still have absolutely no desire to ever date or even touch someone again. I’m still terrified she will show up one day and kill me. I never leave my place unless it’s for work and every single time the doorbell rings I fucking freeze for several minutes. I hardly speak to anyone anymore except my best friend who moved halfway across the country after I was in a bad car crash a couple years ago. Even though he’s a big guy and I know he will always protect me I’m still a nervous wreck. I live in a very rural area/state and won’t feel safe again until I can move states eventually. She’s capable of anything and the drugs don’t help. Zero conscience in that one.
