To report an ex to HMRC for Tax Evasion who cheated on me the whole six months we were together with various others. He told me about his tax evading ways towards the end, before I found out he had been cheating...

I wouldn't, but you do you. If you think it will make you feel better, it won't.

No because you are being petty.

Hell hath no fury like a woman scorned!

Would you have reported him if you were still together?

If you genuinely believe he is evading tax then go for it, if it is just sour grapes then let it go.

Lol OP, do it.

I wish I had something like this to have done to one of my exes.
