He left me for his ex :( Watch
Don't let that stop you from finding love in the future.
Just focus on the important things in life.
- accept and come to terms with the reality of the situation
- do not contact him at all, do not check up on his social media
- actively pursue your hobbies and interests
- if you're a student, study hard and make sure you stay on top of that, you don't want your progress to suffer as a result of this
You're heartbroken, I accept that and I understand it. But you CAN cope!! You can do it. You'll have to temporarily put up with this heartbreak (it's unavoidable) but you have to make sure your life doesn't come to a halt. You have to be productive in your work or studies, and try to get involved in fun activities and hobbies, including socialising with friends and family. I'm sure you've heard it all before, but there's a reason why people always repeat the same advice over and over again, that's because it works. It'll be so tough, but you can get through it, maybe your friends and family can help you, just maybe.
This is just a minor setback, as an outsider I can tell you that it is possible to move on. It's not going to be easy at first but it gets easier bit by bit.
If it helps,what comes around goes around.
