Dating Someone with ADHD

Hi,

I have a lot of friends with ADHD and also a gf of 2x years with ADHD. I do not seem to have it, but sometimes I guess I give off signs that I do. But I think people just like to overdiagnose.

I'm not really sure of the future with my gf. I've seen that ADHD is a legitimate disability and everyone I know who has it seems to be in school for an extra 10+ years and struggle with basic habits.

My gf also seems to bounce around and around to the same thoughts. It gets pretty annoying. I don't really know how to cope with this long term. We may move in together and I'm pretty worried I will get so annoyed with her that it won't work within a month or two.

How do I keep my place peaceful with an ADHD partner? Are there some sort of boundaries anyone has set, like don't speak to me for some amount of time per day so I don't get overloaded? Or you need to do your own thing x number of days per week? I just get overwhelmed by her energy, especially in the morning.

Also, do ADHD people have zero filter? And how do I deal with that?
