If your ex tries to contact you, listen for the first few times, but if it's mean, hurtful, or wanting to get back together when you don't want to, ignore it. Slam the front door in his/her face, hang up that phone, and trash the letters.
Its not an ex-girlfriend. Maybe he calls for a bootycall
it means..they still like you....
If you don't want any contact with your ex, then it is fine to ignore her calls and text.
Tell him to stop and
That would solely depend on you and if you want to talk to him again. Remember he is your ex for a reason are you willing to go through that relationship again...
he still calls you, he asks friends about you, he calls you on your b'day or special occasions
Ex means you are either not their steady dating partner any longer or not their friend.
you don't answer his calls and if you see him and he asks you why you are not answering tell him that you didn't get them.
she calls you from his phone and tell you
It sounds to me like she's using you only until she reconciles with her ex. This is not fair to you nor to her ex. This is considered an abusive relationship.
If he calls you and doesn't speak up he might not know what to say and you should talk to him. He might want to talk with you- as in make up. *It means that your ex calls you with a private number and doesn't speak. Hope that helped some :)
