First, tell her what to expect. I got my partner ADHD For Dummies, which he says has helped him a lot with understanding some of my more wacky behaviours.
You need to talk to her about this stuff. She needs to be aware of the way ADHD affects you, and ALSO what you are doing to manage it. Let her know what your concerns are. If you hold bak affection, she’ll notice and it will make her insecure, which will lead to bigger problems down the track. Taking it slow is good, but she needs to know what you’re doing and why.
My psychiatrist told me that these sorts of issues, where it becomes a bit of a clash, are ones that we need to work on together as a couple if we want it to work. Compromise requires both parties to meet in the middle, not just you trying to mitigate your symptoms while she wonders what’s going on
