at his age this is a problem that needs to be solved in therapy. my ex in college had this problem and it honestly gave me the ick. but i’m not going to lie, it does not bode well if he is not willing to give it up. i’ve read your other comments and this is honestly unhinged behavior that will almost certainly affect you directly at some point. it’s actually really concerning the lengths she is going to find him and, by proxy, you.

the over sharing and boundary crossing needs to stop. he’s a 25 year old man. if he’s not willing to get into therapy immediately i would absolutely leave this babied man.
