But, Although, If only, I wish I had

「手伝てつだって」って言いえばいいものを、一人ひとりでやるからこういう目めに遭あうんだよ。

You could have just asked for help, but you did it alone, and that's why this happened.

Explanation

「ものを」 at the end of a sentence, or joining two clauses, expresses regret or reproach: 'if only..., but instead...'. The first part is usually a conditional (～ば, ～たら, ～なら) describing how a bad result could have been avoided, while the real outcome is the opposite. 「素直に謝れば許してもらえたものを」 (If you had just apologized honestly, you would have been forgiven, and yet...). It carries regret and sorrow, or blame for someone who ignored advice. It often stops right at 「～ものを。」, leaving the regret hanging.

Mixed up with

「のに」 is a plain 'although': the facts differ from what was expected, with a wide range of feeling.

「ものを」 always carries strong regret or blame: 'it could have been so much better, but a mistake ruined it'. It is also more refined.
