My ex girlfriends keeps calling and sending messages to check up on me, what do i do?

Respond. Maybe you don't love her the same. But she loves you. And through pain, she still cares. She wants to know that you're okay and you're doing well. You may not need her as much. But she's always there for you. And she wants you to know that. Her love for you is rare if she texts after a heartbreak. Do not ever ignore a girl who cares. It is hard to find anyone who cares about us. But there is always that one person who does. Sometimes, a good relationship like that leaves that kind of impact on people. It makes us only human to care about your ex.

As she is an ex girlfriend, you have no obligation to respond and are within your rights to block all contact from her if her communications with you are bothering you. I would suggest blocking her number and any other channels she uses to contact you. If you don't want to do that, then you must communicate how you feel to her so she can modify her behaviour and hold back. If she is still contacting you though, this could mean she still has feelings for you. An abrupt shut down of communications is easier than trailing it out with her and potentially giving her false hope, that is, if you're responding to her messages.

Tell her that you do not wish to disclose the information and that she should respect your privacy. If this behavior continues then you should be more assertive and insist that she stop. After continued requests perhaps law enforcement may be able to intervene to end the harassment. It is can become complicated when a relationship goes sour and the split is not mutual, there may still be residual feelings from one or both parties and that can lead to further complications in the scenario. This generally would need to be halted as soon as it begins to prevent escalation
