What do I do if my ex keeps contacting me?

You block him on everything and if he keeps bothering you go to the police and get a restraining order on him

It's always better to maintain a friend,y relation even after real up so u can or he can contact but until in limits it's fine once it seems like stalking u ...u can always avoid :-)

Ask him not to. Explain that you are over and be gentle. You need to let them know that you have moved on so should they.

Ignore them if you don't want to talk to him, if you do than talk to him. Ignoring him is the best thing you can do.

Depending on the situation and how things are left, consider whether you want to speak with him or not. Sometimes contact with exes can lead to more hostility in my experience it's best to the intention and motive of the conversation. If you're personally fine and have moved on it may be healthy of you to refrain from such contact.

depends on why your ex is contacting if you had a bad break up and your ex is guilty and you feel like you can give a chance to them then go for it or otherwise just tell them you moved on and if that's not gonna work block the communications , you know technology leaves you with many choices :)

Understand that your ex may not be as 'over' the relationship as you are. Understand that they are also human, wanting to express themselves. But you are also human. If they only have friendly intentions, so be it, and be friends, nothing more. However, if you feel uncomfortable with them trying to get closer to you than you'd like, calmly tell them that you have moved on and they should to. It won't be easy as they might lash out, but you have to stay strong and understand that they are just letting out their emotions as well because they may be upset that you don't want to get back together. Remember to stay strong. If they still persist, you may need to tell a person close to you or get help from the police if the contacting gets worse until it turns into stalking.

You can talk to them, tell them that you don't want to talk to s/he anymore. That the two of you are exes for a reason. If they keep persisting, you can always block their number if your phone allows you that function.

If it's unwanted contact, I would make sure to state so. If they continue, you can block them on most social media sites, and there are free phone apps that allow you to block numbers. If it gets to the point where it's harassing, you may want to seek further action...

block him on all social media and if you need to don't be scared to contact the police because you deserve to be happy and safe
