I cheated on my girl, what should I do?

say4f
So long story short :
Last month, me and my girl went to a party hosted by one of our friends. She went on and sat with a bunch of her friends and i sat with a bunch of mine. Then, one thing led to another and i regretfully cheated on my girlfriend with a girl i always had a crush on. Now, a month later, i feel like our relationship has become frail as if she realized i am keeping a secret from her. I feel tired of this relationship and i decided to take an action. So the question is :
Should I break up with her and save her the trouble of knowing what i did (which i know will break her heart) or should i just tell her the truth and eventually get dumped by her (same outcome) ?
