He cheated again, no matter how much you both wanted to move on, he always came back to you and you to him

He cheated on his girlfriends countless times to get back with the same ex, you

You did the same, no matter how hard you tried, your chemistry was stronger than anything

You didn't work as a couple, but at the same time you were always together, coming back to each other, it wouldn't be news to anyone if one of you had cheated again to be together
