What do I do if my ex keeps contacting me?

it's a matter or let them or don't. You can go as far as removing them using firm law methods, but I think (in most cases I am familiar with) if it's not a serious issue, it is a matter of finally receiving the love you wanted prior and now they are showing you it. Stick with the initial instincts that told you enough was enough. And if you have the absolute guts to, leave them with this parting note: "You broke my heart. I'm letting someone else mend it."

If you wish to end contact with him then you can politely tell him that you do not wish for him to contact you anymore.

you can ask them politely to stop, if they don't, you could block or delete them on social media/their phone number

It can be really hard to deal with an ex who keeps trying to contact you. If you are under 18, it is much easier than once you are no longer considered a minor. The following steps helped me make my ex realize that I never wanted him to contact me again: 1) Asking him/her to stop contacting you. Keep it calm and polite. If that doesn't work: 2) Telling him/her to stop contacting you. Try to keep calm and try to remain relatively polite. But also know that he/she will try to push your buttons. If that happens: 3) You may need to involve someone else (i.e. a friend who will tell him/her to stop talking to you, getting a restraining order, etc.).

Work out how you are feeling before taking other peoples feelings on board. You are the expert on you

If you don't wish to be contacted, it isn't difficult to block someone on your phone, email, social media etc. Ignoring all attempts works too..after a while of being ignored, people tend to put their attention elsewhere. Hope this helps.

tell him/her you don't want to talk to him and block him if he keeps bothering, you can also call police and ask for a restraining order

It depends what they're contacting you about and why you guys broke up in the first place. If they claim they have changed their ways, test that anonymously, and then make a decision on if they're worthwhile or not. Unless you don't want to get back together of course, but honestly I want to get back together with my ex.... If they are bullying you, then remove them from your life completely. Delete the texts, remove and/or block them on social media, and just don't respond to whatever they say.

You can choose to talk to him and just talk like causal friend. If I oh don't want to talk to him though just block him number.

Break ups can be very hard and sometimes it is difficult for the people involved to let go or accept the reality of the situation. If you do not want your ex to contact you and you have made this clear and their contact is unwanted and causing you discomfort. There are measures you can take such as changing your number and other sources that they are using to contact you. If this persists you could seek legal advice. citizens advice, could be useful.
