What are your personal deal breakers in your relationship

[mmxcm]

And do you always state your boundaries at the beginning or as things develop and progress

I don't 'state boundaries' as I don't see it as appropriate to attempt to police another adult's behaviours and wouldn't tolerate it in reverse. If a question comes up I'll give my opinion, but generally I find that's rare because most people are inherently decent and have a perfectly adequate moral compass that regulates behaviours in a relationship in any case.

If someone does something I find unacceptable then I'll make it known and decide what, if anything, I want to do about it, but I still don't see any need to go laying down the law beforehand because people have a right to free will, even in a relationship, so if someone wants to do something I personally object to that's entirely up to them. I don't have the right to attempt to pre-emptively 'prohibit' it, and I wouldn't tolerate that coming from a partner either as it's low-level controlling behaviour. I'm perfectly capable of behaving myself without having condescending, controlling 'rules' laid out for me.
