ADHD and relationship

So I have a boyfriend and we both have adhd. Every few months I go through phases of wanting to break up with him but it eventually ends and I don’t want to break up with him anymore this usually lasts about a few weeks at a time. I think this is because my brain gets bored with him eventhough he’s perfect and hasn’t done anything wrong. I feel like such a horrible person but I can’t help how I feel eventhough I know it’s probably my adhd. Is this the case for anyone else or is it just me?
