That seems like emotional blackmail, Lostin. Yes, definitely keep doing what you're doing. It was your decision to end the relationship and you have every right to move on. If she keeps insisting you may want to block her so that she won't bother you anymore. Either way, I'd suggest to just ignore her and keep moving on, or perhaps send a last text in which you can explain that you don't want to get back to her and why. Either way, just stick to your decision if you feel like the relationship was toxic to you. She needs to respect your decision and can't force you to come back. Sending many safe, warm hugs to you, Lostin, and to ALL the people you love and who love you!
