He recently purchased a new home with his wife and they are living together.
He does not live with the LDR, sees her every month or two.
...
They are 100% married, not separated.
...
I was just shocked LDR has remained and the affair will seemingly continue for possibly five more years and the wife will never know.
Out of curiosity, how do you know all these?
And as others have pointed out, it does make me look spiteful, even though I ended it, but it looks like - well it didn't work on the LDR, so now I'm going for his wife.
It does but if it truly isn't the case, then that shouldn't matter.
The worry I have, maybe irrationally, is would he instruct a solicitor or whatever to try and intimidate me, trace my account etc.
If i contacted the AP, would contacting the wife be a course of conduct constituting harassment?
I don't think he'll have a leg to stand on, do you? What would be his case? You haven't harassed him so he'll have to prove that he has a reason to instruct anyone to do anything like that. Tracing your account mean hacking - ethical or illegally.
This wouldn't be an issue here. It's more online I would be worried about.
How do you know he isn't capable of physical violence or dangerous revenge?
