Oh that's terrible. I hope you cut off such people from your life. No matter how lonely you feel right now, it's not worth the trouble of being close to them again.

You can always vent out your problems here buddy, we'll give you a listen certainly. I get it feels hard right now but it's good riddance honestly.

Be thankful for everything. Atleast you found the truth now. But don't make a mistake by breaking your relation with them also don't stick close to them as it'll only hurt you, just make them sure that you are happy for them. Focus on your life and let your happy and successful future make them feel guilty. And I'm certain that always people who gets betrayed have a beautiful and perfect future. Surely, maybe it takes time but, you'll find a perfect partner who value you-only you. Hope and move on with a carefree smile:) Everything will be fine.

Damn, that must be hard on you. It's better not to talk to them ever again. And no, you're not alone. You're better off this way than being with people who go behind your back. Also, you're not alone cause even though I'm a stranger to you, I'm all ears and am here to help you move on :)
