What is the best way to stop myself from calling my ex whenever I'm lonely?

Delete all forms of communication with them, this will prevent you, also blocking them will be good as it gives you a choice wether or not to call them. In addition to this you can surround yourself with other positive people and environments. Creating a secure base around you is important to feel supported this could be with friends or family.

How about calling someone else, like a friend or relative? Also do u know if she minds when you call her?

you can take a minute and do some breathing and think to yourself about why you are broken up and write it down or call a friend or family member that supports you

You can always try to do something else. For example, I like to watch TV/read books or just chill with other people.

Giving myself some me time by reading books, seeing films or spending time with friends and family members...realizing that there are better ways/people who can keep you engaged.

Learning to love being alone is quite difficult but once you get the hang of it, you will not only be ' not lonely' but you will also discover how truly adorable and loveable you are.

Delete their number and block them on social media. When you feel yourself getting lonely go hang out with other friends or family. You could even do a hobby that you like.

Spend your time doing something else. For instance, watching a favorite show or movie, cooking, painting, learning a new language, reading a new book, etc. Try to enjoy being with yourself. Talk to your friends or any memeber of 7cups.com. Invest all those emotions to yourself rather than investing it on someone else.Trust me it feels great to rediscover oneself again. :) If your ex is not potentially harmful then it's okay with reaching out to him/her. Sometimes talking and catching up a little might also help with the anxiety you are feeling but if they are not understanding, it's the best for you to distance yourself from them. It's better to be alone than being with a bad company.

I had hard break up. Everyday I thought about that and got hurt. Tried anything possible to get back to my ex, whenever I felt about her. Initially it was tough resisting from reaching her. As days passed by I felt, more I try getting back with her, more I get hurt. I started to something new to divert myself and it helped. Whenever I think about her, I start to do something I love like listening a song or reading a article or playing a game. It's a bit difficult at starting but starts to get better with day

Find someone else that makes you feel the same way to text. I know this may be hard to do at first but if you want to get better you need to take the steps.
