Is moving on from a failed marriage a sin? Must I wait for how long?... So how will you know that enough is enough?...

Not a sin.
When you stop asking yourself that very question...
Then you're ready.

So is acceptance of not being wanted anymore is the answer?

Maybe acceptance of not being wanted by that particular person.

Copy that...

Sometimes it was the marriage that was the sin not the divorce.

no... but I guess in some religions it is ...

how will you know when it is time to move on ...
when you have no more romantic feeling about the x ... and going out with someone else is not wrong ...becouse you are now divorced ...
an feel like you can give your all to someone again ...least for me ... less of course you just want to be free to date and date women ... a understanding of no committees with them knowing that ...

It's not considered a sin after the divorce, but I believe every failed relationship has a chance to renew itself after a short period of solitude. Well, it really depends on what caused it to fail to the point where the thought of wanting to move on was initiated.

Personally, I would keep trying with this person if you think you can recuperate and bring that spark back. Only if the moments weren't dull and you believe you or/and the other person can really work to make things better. Only try till the point where it's clearly apparent that you're not wanted anymore...

I know that, the only way one can truly move on is to find someone else or explore what you couldn't, meet new people. Trust me, I know the feeling of not being wanted anymore, failed attempts after failed attempts. If this is you seeking for answers, keep your head above the water. Time heals everything, you'll figure it out and be ok.

Had an employer, a Franciscan Monk tell me I wasn't divorced from my 1st husband. I was married to my 2nd husband at the time. I am not Catholic, never was, so I therefore promptly put in my 2 week notice. Obviously to him, I was not only sinning, I was prolly damned.
