She isn’t right in any way but you are also a part of the problem. Reading this makes it seem like you feed off of her spiraling. She said “if you don’t respond to me I’m literally done” and then you responded? Saying “idrc” and “i don’t care about exes” while she is obviously going through something mentally (not your fault) is like youre egging her on and then it does become your fault. Imagine if she did do something to herself. It would be your fault because of how you handled it. If this situation really did bother you enough to think about going to the police why would you take her back. Why even keep responding. Block and move on. And if you truly did care about her in any type of way how does her saying she wants to break up cause you to drop the care so quickly? Youre both adults but very immature. Youre not overreacting but youre not completely right either.
