Consider the following sentence:
The simp could not have helped but come/came running the second the girl called him.
Should I use 'come' or 'came' for this sentence? And if I should use 'come', would it be the infinitive or the past participle?
Also, could 'had come' work?
Because 'not..X.. but..Y..' feels like a pretty common structure that negates X and affirms Y. So I feel like X and Y should be of equal status. And in this case, 'could not have helped but ___', X being have helped and Y being some form of 'come' so wait, should it be 'have come' instead?
