I wish they would get help

My nex continues to try and make sure my leash is still there. They reach out every 2-3 weeks to either be a douche or to pretend they still “care” for me. A month ago my nex reached out to ask for money after ghosting me months back, no explanation for the ghosting or why they wanted money, just simply to make contact and tell me that someone else would “take care of them” when I said no. They reached out again yesterday to say they “love” me, when I responded sarcastically asking if they had gotten bored with their newest supply they said “I’m single and have been single.” When I didn’t respond they then sent a picture of a “wedding invitation” to what I assume would be make me feel bad. I just simply don’t understand how they justify the way they treat people and how they think to themselves that they aren’t sick and don’t need help. They are blocked on social media and have me blocked by phone number. Yet they continue to make text now numbers to keep bothering me. I’m mostly venting but truly I hope they wake up and realize they need help at the end of the day.
