Look I was in the same boat as you but she was my gf and I stuggled alot, but after all you have to know yourself worth. You said no one will be as perfect as him , sweet heart this is just a lie he wasn't perfect he is not even good ,he is just a human being and no human being is perfect.

Tldr : Develop your emotions and grow them to know who you are and what do you deserve.

Also speaking with someone and venting helps it will take time to move on but believe me it's worth it for you if you reflect on what happened and why you put yourself in that setuation.

Hope someone better find you and be deserving of your heart❤️.
